TOPIC - AMOD AGL 3080 Data Logger
Driverless - 128Mb Memory - 3AAA - Full NMEA - Push to Log - One Touch Backup




Product page at Semsons : >> link <<
V2.0S firmware update : >> link <<
NMEA to Google Earth Tool : >> link <<

UPDATED BY GPSPASSION 20080312 : AMOD have just made available a new v2.0s firmware with SN (Static Navigation) disabled (see below for explanation on SN). They have also added 6 new logging modes with variations in the update rate and NMEA messages being broadcast. With RMC messages recorded every 10 seconds, the logging life is now up to 120 days. In case that's not enough for you or if you want to backup your data, it is also OTB (One Touch Backup) compatible now (thanks to PrzemekW for checking). More details and links on page 8.

UPDATED BY GPSPASSION 20080222 : After noting some strange logging patterns in pedestrian use, I did get confirmation that Static Navigation is indeed enabled on the v2 models of the 3080 and this cannot be changed. I mentioned that having SN activated for a data logger was not a very good idea as it is likely going to be used on foot quite a bit and they agreed. They are planning to come up with a v3 with SN disabled by default and with the option for the end-user to activate it.


Compared to other GPS Data loggers

UPDATED BY GPSPASSION 20080122: I needed the 3800 for some comparison testing the other day and couldn't remember which one was which, so I take them both on the road and compared the results but first letting them acquire a fix next to my reradiating antenna. The results are quite interesting, the signal level is very different, about a 12dB-Hz difference, which is huge, but the actual tracks are quite comparable on average, except in more difficult conditions, sharp turns for instance, not that surprising really since the SiRFstarIII can work with very low signals, as happens behind coated windshields. The problems are long TTFF and worse accuracy of course.



UPDATED BY GPSPASSION 20071219: Just received a new test unit and I'm happy to report that whatever problem was causing the lack of sensitivity on my previous test unit has been fixed! I can't see any serial number on the unit so I'm not sure how to determine when it was fixed but it's safe to assume that units shipping currently are OK.

I had it stored deep inside my backpack on a train ride and walk around a Paris and it didn't miss a beat.

With this problem fixed the GL3080 goes back to the top of the list of existing dataloggers thanks to it's driverless implementation and also the fact that it records a full NMEA log that you can convert into whatever format suits your needs.

UPDATED BY GPSPASSION 20071031 : An update on the problems noted below, after analyzing some logs I found that the SiRFstarIII chip was being fed very low signal from the GPS satellites, hence the long TTFF (28dB-Hz is needed to download the ephemeris data and get a warm fix) and poor accuracy (due to low/noisy signal). I'm told AMOD have figured out what the problem is and are working on an updated version.

POSTED BY GPSPSASSION 20071012 : While it's very convenient to be able to download the raw NMEA track by just connecting the 3080 to a PC via USB, I'm rather disappointed by the 3080 in terms of GPS performance, it never got a fix inside Paris although I walked around for a good hour and then I saw a lot of "jumping" during a side by side comparison with the HTC Kaiser PDAPhone walking in the streets of Bry/Marne as seen above (HTC Kaiser PDAPhone in red, 3080 in green). It was clipped to the front of my backpack with a good view of the sky.

Pedestrian tracks are always a bit "wobbly", but I've seen much better from SiRFFstarIII receivers.

POSTED 20071010 BY davidw4806 : I received the unit on time yesterday. The shipping package was great and everything was in the box. The AMOD unit comes in a nice box and includes the GPS Unit, a strap that attaches to the unit and includes a swivel clip and a CD ROM. The strap is ok but the clip is plastic and I am not sure how long it will last. The unit itself is well made and the battery door is solid plastic with a good connection, it does not feel like it will fall apart.

The GPS unit is easy to use, two buttons and 3 lights. 1 button is the power button and the other is a mark button.

I put three batteries in the unit and took it outside and powered it up. It took about 2.5 minutes to get its lock but it was the first time it was on since I took it out of the box. Will have to see how long the lock takes on the weekend after it has been sitting in the same location for a few days.

After the initial lock the system showed a blinking light which means it has a good signal. I began a walk around the block. While I was walking the unit was in my hand swinging back and forth. After 3/4's of the walk I held the unit steady in my hand with no movement back and forth.

When I returned home I plugged the unit into my MacBook Pro and it showed up immediately as a drive. There is a folder on the drive that holds all the logs. I took the NEMA log and used GPS Visualizer to convert the log to a GPX file and a KMZ file. Both were created with no errors. The files worked with Jet Photo and Google Earth.

My only issue was the unit had me bouncing all over the place as plotted by the log. I finally figured out that the strange plots were only in the area where I was swinging the unit in my hand while walking. Will have to see if it does this when clipped to my camera strap which is the method I hope to use going forward.

Software:

The CD Rom comes with a copy of Jet Photo for both MAC and PC. Everything is easy to use and I had no issues at all except for the plot bouncing that I probably created myself.

Will give it more tests over the weekend when I have time.

ORIGINAL POSTI ordered the AMOD AGL3080 GPS Data Logger today. Has anyone had a chance to use one for photos yet?

I was looking for a small data logger without a proprietary battery and could go as quickly as 1 second for each log entry. The manual shows the software only reading Lon and Lat. I do not need altitude but I also am not sure what it tracks for those who want a 3D reading of their travels. It is SIRFIII LP driven and is supposed to have a life of 15 hours with three charged batteries. It uses 3 AAA batteries but does not charge any within the unit itself. Universal USB interface requires no driver for Windows or Mac and the log is stored in standard NEMA format.

It appears to be exactly what I am looking for and I hope it stores the entries in one log rather than every 95 like the DG-100 from Globalsat.

I will be sure to write about my experiences when it arrives next week.

In order to synchronize your photos with the GPS data I would recommend using GeoSetter:

OMG! I don'yt understand any of this discussion. I'm a GPS/AMOD newbee... amateur photographer that got tirted of not remembering where photos were taken. I just want simple uncomplicated, perhaps unsophisticated instructions on using the GPS andthe software that came wih it.
Does anyone know of a manual that is more clear than the one thatcomes on the CD?
I have several questions way simpler than the discussion here.

Apparently the Samsung Galaxy Note uses a Broadcom BCM47511IUB2G GPS chip (links here and here)

The Galaxy Note is not bad at all. It is the AGL3080 that is better (yes, I'm impressed and more than happy with its accuracy, specially since I've changed to SN-off).
gpspassion Posted - 03 avr. 2012 : 02:49:48
Thanks for the additional info, still the Galaxy should have done better. I had the TAB at one point and it didn't perform so badly, I wonder what chipset they are using in the Note...

The good news is that the AMOD really did a good job and with its direct USB connectivity (and direct transfer to a jailbroken iPad) I think it's going to become my "goto" datalogger. The Qstarz loggers are nice but it's a hassle to have to use additional software to transfer data.
ceroni Posted - 03 avr. 2012 : 01:12:23
Thanks for the picture resizing. Now I've found out how to do it.

Both devices were positioned on a recess just above the car's glove compartment, very close to each other.
To be fair with the Samsung Galaxy, I've chosen the worst part of the tracklog. In the shown track I was driving very slowly (it's a narrow road in a particularly scenery location with vineyards on the hills). I suspect the Samsung Galaxy has the static navigation turned on, which explains the jumping around of the tracklog. However, I've been unnable to confirm it.

Anyway, after inspecting the whole tracklog I came to the conclusion that the AGL3080 clearly outperforms the Samsung Galaxy.
gpspassion Posted - 02 avr. 2012 : 23:18:18
Wow, the Galaxy Note didn't do well, how were both system positioned ?

[PS - your picture was too large, I resized it and made it clickable for the full size version, should be explained in the picture upload topic ;-)]

Did some more battery testing with two 1000mAh and one 800mah (didn't have 3 of either) and I got 12h11 minutes, so that's significantly less than with the Eneloop AAA's!
ceroni Posted - 31 mars 2012 : 16:08:04
AGL3080 (blue) vs Samsung Galaxy Note (red)

Details:
  • AGL3080
    • firmware 2.4PS (Static Navigation OFF)
    • Mode 3: GGA/GSA/RMC/VTG/GSV -> 5 sec
  • Samsung Galaxy Note
    • GPS Essentials 2.8.6
    • 10 sec update interval

gpspassion Posted - 19 mars 2012 : 18:46:32
Here are the results of my battery testing with the eneloop 750mAh AAA batteries :
-> 17h10 in mode 3 (one recording every 5 seconds with GGA/GSA/RMC/VTG)

Not too bad even if I seem to remember the Globalsat BT-335 achieved a bit more with its massive 1800mAh Li-Ion battery.

Was able to retrieve the log directly on my iPad and then send it to my Dropbox via the iFile application and open it there, neat. Haven't found any log converting application of GPS app that imports raw NMEA files though, only GPX.
gpspassion Posted - 15 mars 2012 : 18:07:10
Had missed this, what do you mean ? Are you finding the logging to be more accurate with v2.5 ?

I upgraded mine to v2.5 but it seems to be available with SN ON for now so I'll downgrade to vZ.4 SP OFF as I'd like to use it when walking.

The power/non-power versions are a bit confusing, at first I thought they required new hardware but apparently not. I chose the Power version (recharges when you plug it in) but the lack of a charging indicator is also a bit confusing. Still it will come in handy to recharge during car trips.

I'm going to try to plug it in my iPad with the USB adapter to see what happens...

CONTINUED : well with the USB connector from the Camera kit, a jailbroken iPad and iFiles you can read the content of the AMOD! Now to find a way to convert NMEA to GPX on the iPad or an app that takes raw NMEA logs as input.

============================================================================================================
The V2.1 firmware described below

Bugs fix:

==> Fix the bug that the device still has create the same name folder before user create "GPSFILES" folder.

============================================================================================================
The V2.0 firmware adds a "Setup Mode" described as below:

1. Original "DISC RESET" operation by holding both "POWER ON/OFF" button and "MARK" button simultaneously to clear up the storage space has been removed. Holding both "DISC RESET" and "POWER ON/OFF" buttons simultaneously will enter "SETUP MODE".

2. New function (SETUP MODE) and operation procedures is added and described as below:

** Operation procedure **
(1) Power off the device
(2) Initiate "SETUP MODE" operation by holding both "POWER ON/OFF" button and "MARK" button simultaneously for 5 seconds. When you hold both buttons, the three LED will flash 5 times and stop at light on mode. You can release the buttons when three LED lights are all on.

** "SETUP MODE" Function description **
(1) Logging mode setup:

AGL3080 has 6 logging modes. You can change logging mode by pressing "MARK" button. For each press of the "MARK", it enters to following logging mode. Pressing "MARK" at "Mode 6" will bring you back to "Mode 1".

Logging Modes and corresponding LED status are described as below:
_________________________________________________________________________________________________________
| | | | | |
| | LED Status | Output Format | Records at least | Using Time at least |
|___________|_______________________|_________________________|____________________|______________________|
| | | | | |
| Mode 1 | Memory Full Led ON | GGA/GSA/RMC/VTG->1 sec | 260,000 | 72 hours |
| | | GSV -> 5 secs | | |
|___________|_______________________|_________________________|____________________|______________________|
| | | | | |

|___________|_______________________|_________________________|____________________|______________________|
| | | | | |
| Mode 4 | GPS Led Flash | Only RMC->5 sec | 1,040,000 | 1440 hours |
|___________|_______________________|_________________________|____________________|______________________|
| | | | | |
| Mode 5 | Battery Low Led ON | GGA/GSA/RMC/VTG->10sec | 260,000 | 720 hours |
|___________|_______________________|_________________________|____________________|______________________|
| | | | | |
| Mode 6 | Battery Low Led Flash | Only RMC->10 sec | 1,040,000 | 2880 hours |
|___________|_______________________|_________________________|____________________|______________________|



(2) Clear Disk function:
==> Hold "MARK" button for 5 seconds to all three LEDs start blink sequentially, then release the button to clear up the storage space.
(3) Special features:
(a) The device would power off during setup mode if you do not press any button after 1 minute.
(b) If system power is low, the battery led will be on and then device will be powered off. At this
time, user have to replace new batteries.
(c) User's each change of the logging mode at the setup mode is recorded by the system. If the
system is cut off power unexpectedly, the last setting value before power off is recorded. Therefore, the system power on at
GPS mode, it will run at the last setting value.



3. This "V2.0" vesion is default for AGL3080 device.
The default value of this device is with Static Navigation(SN) "ON".
The other version "V2.0S" is with Static Navigation(SN) "OFF".
=> How to identify from two different versions?
If it's default version (V2.0), Storage LED will flash "twice" after all three LEDs are
on and then off. The GPS LED will start blinking when the device starts tracking successfully.
If it's "SN OFF" version (V2.0S), Storage LED will flash "three times" after all three LEDs are
on and then off. he GPS LED will start flashing when the device starts tracking successfully.

What follows is a compilation from several forums and blogs:

The static navigation mode has been introduced for road navigation, to avoid permanent changes of the coordinates, that would imply continous recalculation of itinerary and continous map movements. Static navigation is a position filter designed to be used with motor vehicles. When the vehicle’s velocity falls below a threshold, the position and heading are frozen, and velocity is set to zero. This condition will continue until the computed velocity rises above 1.2 times the threshold or until the computed position is at least a set distance from the frozen place. The threshold velocity and set distance may vary with software versions. Some references say that velocity's threshold is about 5 Km/h, thus for any other use of the GPS other than car navigation (ie, for using when walking) you must turn off the static navigation mode.
Some versions of the AMOD AGL3080 shipped with a firmware setting known as "Static Navigation" turned On. If Static Navigation is On, the GPS will not update its location whenever it thinks you are not moving. This can be useful for automobile satnav devices, but for geotagging it is not recommended, especially if you are moving slowly on foot. Immediately after the device is turned on, the Storage indicator will blink to indicate the firmware setting. If it flashes 3 times, Static Navigation is Off and actual position fixes will be recorded. If it flashes only 2 times, Static Navigation (SN) is On and motion-filtered position data will be recorded. In this case, you may want to update the firmware to a version with SN Off.

hello
What is the firmware static navigation SN on SN off
Can I install version 2.5 feet for a walk
?
thank you
ceroni Posted - 16 déc. 2011 : 13:31:11
AMOD download page (http://module.amod.com.tw/Support/download.asp?tLGIqc6FuoJI) now has the latest firmware (version 2.4, both static navigation ON and OFF).
ceroni Posted - 15 déc. 2011 : 12:42:27
Installed the 2.4P (static navigation off) firmware AMOD has sent me by e-mail (using Windows 7 64-bit).
Works fine. Comparing to previous logs of the same paths (using 2.4P original, static navigation on), there were no effects on tracks while moving by car (city traffic) and tracks were much more accurate when walking.
ceroni Posted - 13 déc. 2011 : 11:02:26
Just received an e-mail from AMOD with answers to my questions that could be of interest to others:

-Does the "2.4P" in the first line of the log file really indicate a 2.4 firmware version in my particular device?
-Yes.

-What does the "P" stand for?
-It stands for Power(Rechargeable) version.

-I've noticed that some firmware versions have a "S" after the number. What does the "S" stand for?
-It stands for Standard version.

-Is it safe to downgrade from firmware version 2.4 to version 2.3? What functionalities and corrected bugs will be lost?
-No risk there~ but we suggest you to adopt attached v2.4.

-When the 2.4 firmware version with Static Navigation (SN) turned OFF will be available?
-Please find it in attachment.

-Are there any plans of releasing a firmware that allows to turn Static Navigation ON/OFF using a simple set up option (like changing logging modes)?
-No…the changing mode function is in configuration which can be set up by users; but firmware is not settable by users.

-Is the 2.5P firmware available at Motion Gears an official version from AMOD? Can it be safely used?
-V2.5 is customized for specific customer. It might not proper for you.

-Is it possible to use Windows 7 64-bit to perform firmware upgrades?
-It should be fine!

-Is it possible to recharge the batteries using the USB connection while logging is in progress?
-Yes you can do that.

I'd say try finding someone with a newer computer that they'll let you borrow... I think your problems might be from the age of the computer hardware itself.



Yes, finally tried it with a more recent Dell Windows Laptop (USB 2.0 Ports, previous system has only USB 1.0 ports) - and again Windows XP (XP seems to be still quite popular).

And with that system the firmware upgrade worked (as administrator).

To sum it up: The AMOD firmware updater is a bit picky about hardware while being not very diagnostic about it and I am very shocked how usual it is in the Windows world that a random untrusted binary needs to have root access - and Windows users don't seem to bother ...
ceroni Posted - 12 déc. 2011 : 22:20:25
Thanks for the information on Win7 eaglekepr. In the meantime I've written to AMOD. Hope they reply soon.
eaglekepr Posted - 12 déc. 2011 : 21:53:33
I can't answer your version questions (and I don't have my logger anymore) but I have switched firmware using Win7 64 bit. Any Windows version seems to work.
ceroni Posted - 12 déc. 2011 : 19:20:14
I've recently acquired a AGL3080 GPS data logger in order to geotag my photographs.

I would like to change to a firmware version with Static Navigation turned OFF, in order to achieve a better accuracy when moving slowly (when my device is turned on the red Storage indicator blinks 2 times, presumably indicating that Static Navigation is On).

I've noticed that the first line of the log files generated by my device ("$ADVER,3080,2.4P") is presumably indicating that it is using the 2.4 firmware version.

However, the latest firmware available on AMOD download page (<http://module.amod.com.tw/Support/download.asp?tLGIqc6FuoJI>) is version 2.3.

My questions are:

  • Does the "2.4P" in the first line of the log file really indicate a 2.4 firmware version in my particular device?

  • What does the "P" stand for?

  • I've noticed that some firmware versions have a "S" after the number. What does the "S" stand for?

  • Is it safe to downgrade from firmware version 2.4 to version 2.3? What functionalities and corrected bugs will be lost?

  • Is the 2.5P firmware available at Motion Gears (<http://www.motiongears.com/en/community/downloads/firmware_agl3080>) an official version from AMOD? Can it be safely used?

  • Has anyone sucessfuly used Windows 7 64-bit to perform firmware upgrades?


Many thanks in advance for clarifying these matters.

Hello, v 2.5P : http://www.motiongears.com/en/community/downloads/firmware_agl3080
eaglekepr Posted - 29 oct. 2011 : 00:42:39
You should be able to use ANY Windows computer, you're not limited to Win XP. Pretty sure the Release Notes file just isn't updated. I've switched back and forth between the 2.3 SNOFF and SNON firmware multiple times with Windows Vista and I imagine it should work fine on Win 7 also.

I'd say try finding someone with a newer computer that they'll let you borrow... I think your problems might be from the age of the computer hardware itself.
dud Posted - 28 oct. 2011 : 22:09:56
I have problems to upgrade the firmware of the AMOD AGL 3080. I bought it ~ 2 years ago - and it contains probably the 2.0 firmware (it includes the 'setup mode' which is listed in the release notes) and it has static navigation enabled (because storage LED is flashing two times on startup).

Because I need to disable static navigation (SNOFF), I need to upgrade to SNOFF-firmware. Looking at the firmware upgrade package from AMOD and reading this thread I understand that I need to flash it under Windows XP (or perhaps Windows 2000) as 'administrator' user.

This is really annoying because I didn't have any windows systems. Just for one firmware upgrade I commissioned an old Pentium II (with onboard USB1 ports), organized a Windows XP (SP3) install CD and installed it from scratch on that system.

Unfortunately, (logged in as administrator) the firmware 2.3S upgrade tool (GoNoGo.exe) directly crashes after starting it.

When I 'safely remove' the USB device, the GoNoGo.exe doesn't crash, but it can't find the 'UFD' device.

I issued an 'DISC RESET' on the (disconnected) AGL 3080 - which did not change anything - the GoNoGo.exe still just crashes.

I mailed AMOD and the vendor of the device, but didn't get any replies.

Perhaps someone knows some condition/dependency the firmware upgrade tool needs on Windows XP?

Or perhaps someone has a link to the 2.2 (SNOFF) upgrade?

(The AMOD-special-experts only provide the latest 2.3 upgrade on their great 'support' webpage.)

It seems the 2.2 upgrade uses another upgrade executable (and from the release notes it already adds NMEA format conforming position mark support).

(Of course - deploying a firmware upgrades like AMOD does is pathetic. They fail in so many ways it is not even funny anymore.)

somebody now if a a new release of this gps will go out soon?
102978372 Posted - 15 juin 2010 : 01:55:32
Okay, thanks. That is a little disappointing.

No, the AMOD can only be powered by three AAA batteries. And no, it doesn't charge off of the USB either. USB is solely there to transfer track logs to the computer. If it is currently on and recording a track, plugging it into a USB port automatically switches the unit off (GPS tracker) and changes it into a simple 128MB flash drive.

Hi everyone,

Quick question on the AMOD AGL3080.

Is it able to run on USB power (ie external/vehicle power source) with or without batteries?

Edit: BTW, I have no expectation of battery charging.

Ahhhh ok. I thought I read somewhere in here that distance was part of it too, but I hear what you are saying. Ok so no SN for me. Thanks for the GPSBable tip too. I haven't had the chance to play around with it yet using a decent log but this weekend I'll have a chance for sure.
eaglekepr Posted - 06 avr. 2010 : 07:30:33
The static navigation is based on *speed*, not movement. It only logs a data point if it realizes you are moving faster than a set speed. I've had walking tracks with SN on where there were hundreds of meters between points simply because I was walking slowly.

For smoothing, you can use GPSBabel to throw out any high-error points and set the threshold for what you want. It's not perfect but it helps.
Jumperalex Posted - 06 avr. 2010 : 04:06:32
So here is a question: for the most accurate hiking trail log, especially as far as distance traveled is concerned, it seems like logging every 5 or 10 seconds would be best to minimize the number of back and forth erroneous data points which would add extra distance.

Along those same lines, my understanding is that part of the problem with static navigation turned on is that it can give bad tracks if you haven't moved far enough between each logged data point. But logging every 5 or 10 seconds would seem to give plenty of distance for SN to not cause problems while moving, and would avoid "random walk" while standing still, like say taking a picture and enjoying the view.

I ask because a guy on a hike last week used his Droid to log the hike and it said we went like 10 miles but we really only did 7 based on topo maps of the trail. Looking at his log it was clear it thought we zig-zagged the whole way. We didn't of course :)

Thoughts?

I suppose I could write a script to do some path smoothing [shrug], even get really crazy and do Kalman Filtering but I'm not that motivated :-O

Thanks for your replies, the original problem, the frozen lat & long in the log, is persistant.
I did 3 short outdoor tests and 2 of them were corrupted with the error.
I tried to update the firmware in Parallels v4+Windows XP without succes, the process was stopped with an error message.
I contacted the vendor (online shop) and they will take the logger back and sent me a replacement.

I've tried that with Sun's Virtual Box and XP but for the update you need a real hardware Windows PC with administrator rights. Emulated Windows doesn't work.

Hello guys,

This is my first posting on this forum. I don't have much experience with GPS loggers, the Amod AGL3080 I got today is my second one (the first is a outdated Garmin Etrax Venture). I want to use the Amod logger for tagging the EXIF info of DIY streetview panoramas.

I did a short test walk of a couple of hundred meter with both devices side by side and it is clear that the track of the Amod on the GPSVisualizer map is much smoother and a little more precise then the old Garmin.

But this I why I post this message, at the end of the Amod track I miss approx. 15-20 meter so the line of the track stops abrupt while the Garmin is going on.

When I inspected the log file of the AMOD it was clear that the last 20 seconds of the log all had the same location, so the time was different (1 sec adding between the points) and the number of satalites was different in some of the points but the latitude and longitude of the last points are all the same as they are "locked", hence the abrupt stop of the track line in the map.
At this moment the Amod is using V2.2, this is stated in the first line of the log ($ADVER,3080,2.2)

Q) is this something that can be solved by loading the "S" version of the firmware ?

I can try to connect the Amod to my MacBookPro with Parallels V4 running WindowsXP to run the firmware exe but before I will try this I like to know if the "locked" postion issue is related to the default firmware.

Thanks for reading.

Wim

Use the mode when logger save data every 10s, so you can consider Mode 5 or 6. You can also switch it off, when you will have a break or spend the night.
planetbob99 Posted - 20 janv. 2010 : 00:05:00
This might be a silly question. But I am thinking of buying the AGL 3080 for an upcoming trip. Now while batteries wont be an issue, I will just take a shed load of AA's! I won't have access to a laptop or PC to download the tracking data. Will the memory be enough to store ten days tracking out in the Sahara Desert? It would be on most of the day while walking. Also what logging methode would you suggest?

Cheers.
dwd Posted - 05 janv. 2010 : 08:22:05
Hi!.

Just bought the AGL3080 and have tested it for a week.
It came with fw 2.2, but upgraded it successfully to 2.3 Static Navigation off,(using winxp with admin)
Just a caution, i duplicated some files on the AGL3080 using finder on mac, and after that the AGL3080 couldent write gps files to the filesystem, verified it using a reset to the filesystem, then put the gps on tracking again, shut it off, did tracking again, 2 files was created, duplicated some files on the filesystem, then did some tracking again, didnt work.
So. do not write to the filesystem on the AGL3080. it will then stop to track files.
if you do, just reset it(power+flag ~10sek, and then 5sek on the flag button(it will remove all files))

Hey Guys..

I apologize if this has been asked before but I haven't found it yet.. I have just purchased the AGL 3080 and updated the firmware to the 2.3 Static Off... Or attempted to.. Now my machine dosen't recognize the device, and when I power it on, all the LED's are solid and I can't seem to make it do anything else.. Anyone have any suggestions as to what I should do? I was hiping to use it on a trip for a week the end of this week to geotag my photos.

Thanks!

For my own testing, I've used the Energizer "Advanced Lithium" (yellow package) AAAs and have gotten up to 23 hours before it shuts off. Problem is these are relatively expensive at around $6-7 for a 4x pack...


Please note that the lithiums I am referring to are different than the energizer ones. The 10440 (10mm diameter 44mm tall) lithium rechargeable batteries are the same size as AAA but the voltage is 3x. If you use them as is you will most likely fry the AMOD unit. The modification I am talking about doing is so that the 3 would be hooked up in parallel instead of in series. I'll see if I can draw a picture of what I am thinking about doing later.

quote:

Best I've gotten out of them is about 9 hours and they seem to do the same thing toward the end of their power capacity where it takes a lot longer to acquire a signal, and it may or may not record a new track past 6 or 7 hours. But being rechargeable they've paid for themselves after a few charges.


That is odd. A couple of posts up someone got 20hours on maha 1000mAh batteries. How old is your unit? I am wondering if there was some improvement in the battery life along the way. What version of the firmware is on yours? Also most battery guys are known to claim higher mAh than reality.

quote:

If you find out voltages before I do, please post back... I've got 4 batteries from my old Canon Rebel XT that I wouldn't mind figuring out a method to connect. Should last better than any AAAs and be faster to recharge as well.


I am not sure about the XT batteries, but if they are like my 20D was then they are 7.4V batteries and they will not work. The 20D ones actually have 2 AA sized lithium cells (aka 14500) inside them hooked up in series which is why you have 7.4V (2x 3.7).

If you have not used these style of lithiums before you should read up on them a bit before jumping in. They do not like to be over charged or over discharged as that will ruin them. You need to have a proper charger to use with them that will not over charge them over 4.2V. Also the device you use them in should not run them completely dead. I think less that 2.3V or so will kill them. There are some protected versions of these that will not allow for over charge/discharge but not in the 10440 size. I get my batteries from http://www.batteryjunction.com also you can learn more about batteries from http://www.batteryuniversity.com/index.htm

If I don't go down this path and stick to normal NiMH AAA then I am going to use the Sanyo eneloop batteries. They are not as high mAh but they hold their charge for a very long time (85% after 1 year) and are highly regarded. That way I won't have to worry about leaving some batteries on the shelf for a couple months before using them.

@eaglekepr: I experienced same kind of problem recently using 800mAH Varta Ready2Use batteries. Green light was flashing but there was no file stored in the flash memory.
eaglekepr Posted - 21 août 2009 : 11:14:16
I haven't... although I do still have some "dead" batteries somewhere from it that I could test for you.

For my own testing, I've used the Energizer "Advanced Lithium" (yellow package) AAAs and have gotten up to 23 hours before it shuts off. Problem is these are relatively expensive at around $6-7 for a 4x pack... and you need three packs before you don't have any extras laying around. I tried the Energizer rechargeables (green package 800mAh) but I couldn't nail down a time. It seems that there might be a point where the batteries don't have enough mAh left but enough voltage to keep the device running (not a battery expert, so this is a guess). The AMOD was on and green light flashing as though it was operating, no orange battery light, flashing or otherwise, but after I plugged it into the computer, it hadn't recorded a track. This was after a few hours of use. It seemed random whether it would record or not and didn't become reliable again until I reinstalled the firmware (even after fresh batteries).

I've since switched to CTA Digital 1200mAh rechargeables http://www.bhphotovideo.com/bnh/controller/home?O=cart_accessories&A=details&Q=&sku=505231&is=REG from B&H

Best I've gotten out of them is about 9 hours and they seem to do the same thing toward the end of their power capacity where it takes a lot longer to acquire a signal, and it may or may not record a new track past 6 or 7 hours.

just got an AGL 3080. I am wondering if anyone knows the minimum voltage that will drive this thing. Has anyone measured what their batteries are down to when this thing finally powers off?

I ask because I am thinking of making a simple mod to the battery compartment to use lithium rechargeable 10440 batteries (same size as AAA but different voltage). These have an operating range around 3.6 volts so I would have to use them in parallel. This can easily be done by putting all the batteries facing the same way and making sure they are all connected on both ends. You could use just one, 2 or 3 and the nice thing is that they can be charged individually (don't have to be in pairs) and you would get about 50% more mAh with 3 of these.

Anyone tried this? Am I nuts for wanting to do this? Any thoughts?
waldo000000 Posted - 15 juil. 2009 : 11:13:44
BATTERY TEST RESULTS:

I have bought an AMOD AGL 3080 and am pleased with its performance.

Last night I charged up 3 Maha Powerex NiMh AAA 1000mAh batteries (http://servaas.com.au/maha-powerex-nimh-aaa-rechargeable-batteries-1000mah-2pk-p-37.html), inserted them into the unit, set the unit to log full information at 1 second intervals, and left it sitting on a windowsill.

Eventually it started flashing the red battery light, but I let it keep going. I only turned the unit off when the red battery light stopped flashing and changed to constantly on.

I downloaded the log (19.8 MB), and checked the timestamps...

The track was 21 hours and 13 minutes long. Lovely. Oh, and the track looked fairly nice - wobbling around the correct location generally within a 25m radius, and only rarely outside a 50m radius.

I have just discovered that there is a plug-in to geotag in Adobe Lightroom. Has anyone used this yet?

If you're referring to Jeffrey Friedl's Geoencoding Support plugin (http://regex.info/blog/lightroom-goodies/gps) then yes, I've been using it since October 2008 when it was first released. It is an EXCELLENT plugin with multiple ways to tag photos either with coordinates you provide, tracklogs, importing from Google Earth and so on. It allows you to do all of your photo management in one program instead of needing two or three separate programs to do the same thing.

How do I switch between SN Off and SN On modes?

Thanks

gpspassion Posted - 25 mai 2009 : 11:04:49
No, the only time you'll notice SN OFF when driving is when you're sitting at a light and the position will wander. It's only really a problem when you're relying on the GPS for road guidance as SN OFF might generate a spinning map (on software that doesn't do its own SN) which gets people confused/upset.
wayhop Posted - 21 mai 2009 : 16:36:51
Doug2311 and Keeshu again, thanks for your valuable advice. (I received my battery charger and batteries yesterday only to find that the charger was DOA. Luckily, there's 2 weeks before I leave to get another one.) I think I'm ready on all other fronts except the SN ON or OFF.

I guess the question would be: are the results driving with SN OFF as bad as the ones walking with SN ON?
massib80 Posted - 21 mai 2009 : 12:02:04
Hi!
I just bought the AGL, and connected to my mac trough bootcamp in order to flash it with the SN off firmware.
After that I connected it inside OSX just to be sure that it works (and worked)

In the morning I set the AGL on MODE2 and walk to my office.

In office I plug the AGL on my PC (WIn) to download the logs... and SURPRISE!
The unit had TWO folders with the same name (GPSFILES) both empty (pluse the hidden OSX files)

I suppose that, somehow, OSX+Win messed up the filesystem of the unit.
I delete all the content trough Win and tested again, this time I had ONE GPSFILES folder and the log file.

I just want to be sure it doesn't happen again! Could be Spotlight? OR... I just got unlucky this time? never happen to any of you?

"The 3080 will eat through a set of batteries in 5-8 hours depending on how good coverage is, so in the course of a day wandering around on vacation, it's not uncommon to have to swap out batteries mid-afternoon."

True, and don't forget to switch the AMOD to OFF before swapping batteries. Also, don't wait until the batteries are dead because both situations will lead to loss of the last data file.

If you switch off and then replace batteries, the file will be closed normally and a new file will be opened when the AMOD is switched back on.
doug2311 Posted - 19 mai 2009 : 18:51:43
I did a 3-week trip last year and the 3080 makes a fine traveling companion. Your husband will be quite pleased with it and it should earn you some great brownie points. :-) A few tips:

1. I completely agree on Houdah GPS and GPSPhotoLinker -- both are great programs. Rather than Houdah GPS, though, I slightly prefer GPS Babel (http://www.gpsbabel.org/).

2. Be sure to sync your camera's internal clock to an atomic time source like www.time.gov. The more exactly synchronized your camera's clock is, the less fiddling you'll have to do later with time offsets.

3. The basic flow is of how to use this whole setup is to first copy the .log files from the 3080 (when you plug it in, it looks like a thumb drive), then use Houdah or GPSBabel to convert from "NMEA" format into "GPX" format, and then finally import the gpx file into GPSPhotoLinker along with your photos to do the tagging/merging. GPSPhotoLinker has a good tutorial so you won't have too many problems.

4. Rather that use Mode 5 on the 3080, I prefer Mode 4 for multi-week trips, especially if you're not going to have a computer with you to download gps log files at night in your hotel, etc. Mode 4 (RMC) provides all the data you'll really need for linking photos and for plotting your course afterwards in Google Earth (use Houdah or GPS Babel to convert to .kml format for Google Earth). Mode 5 just provides additional data on satellite visibility and redundant/expanded location info, none of which are truly necessary. If, on the other hand, you're going to download the GPS files every day or two, you can just use the default Mode 1 and not bother messing with it.

5. I'd strongly recommend that you buy a dozen rechargeable AAA batteries (the 3080 takes 3 at a time, so a 12-pack gives you four battery changeouts) and bring along a charger that accepts 120/240V plus some adapter plugs for Europe. The 3080 will eat through a set of batteries in 5-8 hours depending on how good coverage is, so in the course of a day wandering around on vacation, it's not uncommon to have to swap out batteries mid-afternoon.

Hope this helps. Have a great trip!

wayhop Posted - 19 mai 2009 : 18:35:54
Thanks Keeshu. Mac info is really valuable as we are both about to switch back to the Mac after almost a 20 year PC stint. I think I'll hold on to my PC, though, for things like these firmware updates.

I have just discovered that there is a plug-in to geotag in Adobe Lightroom. Has anyone used this yet?
keeshu Posted - 19 mai 2009 : 18:30:19
To translate the file made by the AMOD to something that can be understood by other programs, use HoudahGPS: http://www.houdah.com/houdahGPS/

For linking the photos to the GPS data I'd suggest GPSPhotoLinker: http://www.earlyinnovations.com/gpsphotolinker/

Both programs are freeware and run on MacOS.

Thanks to all of you for in-depth, educational posts. I am buying an AMOD AGL 3080 for my husband for his birthday. I think the majority of the time he will be using it for geotagging, but I can see him using it for other things as well. I intend to give it to him on the plane on the way to Germany. I'm guessing that he will want to track our car trip from the airport since it's fun to play with a new toy right away. Since it will have to be set up by me between now and then, I need some advice.

For three weeks, we will be bicycle riding, taking photos on foot and doing three 5+ hour drives. Given this, should I initially set it up as SN ON or OFF? I've tried to figure it out from other posters' experiences, but I'm still not sure. I'm guessing that Mode 5 is probably the best compromise on accuracy and battery life.

He will be a whiz at working with it once he gets off the plane and his computer set up, but I'd really like him to have a good first experience. I've got decent computer skills but none on the GPS side. I will have a PC with me but he will probably have a Mac. Is there any software you recommend I download to my machine or have on a cd that he can install on his Mac? He is a software programmer by trade, so the software has to be good but can be sophisticated if there's something that fits that description.

Thanks for your help.
gpspassion Posted - 14 mai 2009 : 13:01:20
The Locr PC software is nice in that you can correct the time in small increments in case your camera was off, can be needed if pictures were taken from a moving car.
doug2311 Posted - 14 mai 2009 : 01:54:34
Generally, the easiest way to sync is to make sure that your camera's internal clock is set to be as close as possible to atomic clock time. I tend to use www.time.gov as my source for the exact, precise time and just set my camera to match as best I can--usually within less than a minute of error. Your GPS unit will also synchronize itself automatically to atomic clock time via the GPS satellite network and embed that timestamp along with each location fix in the GPS files. Now, when you use GPS Photolinker, both the timestamps in the GPS file and the timestamps embedded in the EXIF headers in the picture files will match up and you'll have photos that match up to the correct location.

One minor note, if you set your camera to your local timezone (in my case, US Eastern Time), then you'll need to set an appropriate timezone offset in GPS Photolinker (-5 hours normally, -4 hours during daylight savings time).

You really don't need to use the "mark" button on the Amod. I've never found a good reason for using it as long as your camera's time is set correctly.
asopuma Posted - 13 mai 2009 : 23:47:17
Hello,

How do you sync logs and photos ?
I use GPSBabel+ to convert NMEA to GPX then GPS PhotoLinker (Mac OS X).
I expected to match a photo shot when I pressed the mark button to create a waypoint but PhotoLinker doesn't give any time for the waypoint.

Has anyone checked the NEMA strings and compared them to the release notes ?

I was looking at a log when I was in Mode 5 and it includes GSV data.

The release notes I read says it should only have, GGA/GSA/RMC/VTG->10sec , in mode 5.

As you can see below from the 3 points I've listed that the time in the string GPGGA is showing its recording every 10 seconds.

I haven't checked the other modes yet but if this is correct then then the number of points and the using times are wrong as listed in the release notes ?

Am I missing something here ?

Thanks in advance.

Newly released AmodGPSTracker 1.3.11 seems to work OK. I especially enjoy the cute function "Play".

Just to let others know that it's not possible, the device effectively switches off when plugged into a USB port.
magrolino Posted - 31 mars 2009 : 07:34:28
I tried that once but could not succeed. If anyone was/is successful with "live streaming" the log data it would be interesting to see how he/she did that (but I am not hoping).
Edgemaster Posted - 31 mars 2009 : 01:27:43
I've had a look through the thread and have seen no mention of whether the unit will continue to log when connected to a PC via USB.
I was wondering whether it's possible to stream the NMEA data to the PC live by just 'tail'ing the file (as is possible with most linux files).

@trs2004: Thanks for the feedback. I saw those images, and I have experienced similar results with my Wintec, which is what made me question whether or not the supposedly better chipset in the AMOD would yield better results or not. Also, the buildings in the images on page 9 don't appear to be very tall — I'm particularly interested in how the AMOD performs among highrises, and whether it would perform better than the Wintec in those conditions.

Cheers!
trs2004 Posted - 20 mars 2009 : 04:00:46
On pages 7 and 9 of this thread you'll see some pictures of this unit being tested in an urban environment. Standing still, it wanders around a central point, moving it's pretty good, only becoming confused near tall buildings or other sky-hiding structures.

AMOD Accuracy in Urban Areas, Particularly When Standing In One Place?

I have a question for owners of the AMOD AGL-3080. I am interested in it as a mac-compatible GPS logger for use in urban areas with tall buildings. I am currently using a Wintec WBT-201, and I find that its accuracy falls off when I am in an area with tall buildings, especially if I remain in one place for a few minutes. Would the AMOD with the Sirf StarIII chipset perform noticeably better than the the Wintec in these conditions, or is an urban environment a challenge for any GPS device, regardless of the chipset?

If anyone has both of these loggers and could post comparison tracks walking around and standing still in an urban area with tall buildings, I would appreciate it!

Thanks in advance!

I just found out that using Amod Display on Google Maps the coordinates East are changed in West. Photo coordinates N52 E 4 are shown on Google maps on N52 W 4. This is a location is the sea, resulting in no map. Does any body know how to solve this?

What I don't like about the AMOD is the time it needs to sync to the satellites when just switched on. It sometimes takes more than five minutes to syncronize. That is way too long. I have to remember to switch it on before I leave the house.

rkay Posted - 04 févr. 2009 : 03:42:56
Amod customer support came through and provided me with a version 2.3 firmware with SN off. I was able to install this and tested that it worked as hoped. It was not explained if there could have been any hardware changes, and I don't know why version 2.3 is not on their website.

But it doesn't look like anything significant is provided by this incremental version update. I will copy the beginning of the release notes here:


Release Note:
===============================================

=> Improve the rate of this condition that three leds would flash at the same time during startup
AGL3080 device.

===============================================
The V2.2 firmware described below

Postion Mark function issue:
=> Add support standward $GPWPL NMEA format, and still keep our position mark $ADPMB format


===============================================

Hi rkay
I have the same question you posted recently regarding 2.3 vs. 2.2 firmware for the AMOD 3080. Have you tried downgrading yet? Was there any difference in behavior? TIA,

Arlo

confusing, yes but logical from a power point of view. If the blink rate is such that the light is off half the time, then the power will last twice as long. And since the point of the exercise is to log data all day long, it makes perfect sense, once you get used to the idea.
rkay Posted - 01 févr. 2009 : 02:16:58
That's correct, on their site they only have downloads for version 2.2 firmware. I would have no way to know if the hardware changed on my unit running 2.3 or if it could accept the the 2.2 firmware or how I would undo the process if I messed something up.

I was just hoping to get some kind of response from them, but I have failed.

afaik 'blinking' means that everything is fine, that the unit 'found' its position. my amod stays green as long as it is searching for satellites, after that it starts blinking green. when the batteries start to die there is another red batterie warning sign flashing.

that is very confusing in the first place, I know. I lent my amod to 2 people and both were confused cause usually flashing indicates a malfunction... well, not with this green satellite led :) hth

I received my 3080 last week and have been having problems with it ever since. When I turn it on, the green light goes on. Within a minute, all three LED lights start blinking. I have used two different sets of fresh batteries, have tried turning it off then repowering (as the AMOD website recommended). Now what? I had high hopes for this unit. It communicates perfectly through a USB connection w/my Mac, but there is no data and I don't know what to do to get it working. The AMOD website said to call their support folks, but when I tried the phone number listed, it did not work. Help?
gpspassion Posted - 01 févr. 2009 : 00:34:49
Welcome to the forums. There's really no way to say for sure without trying it. I take it the v2.3 FW is not available on the AMOD site?
rkay Posted - 31 janv. 2009 : 23:28:31
I purchased an AGL 3080 in the last few days and it appears to be writing out a log from version 2.3 firmware:

$ADVER,3080,2.3

I really need to have a version with SN off for walking instead of driving, but there is no such thing as V2.3 SNOff.

I have an immediate need, do you think it would be OK to use 2.2S on this device?

I have written both Semsons and AMOD directly with no answer.

No, the AMOD stays in GMT (UTC) always. You set your camera to whatever the local time is and then tell the difference to your geotagging software so it can line-up the photo with the AMOD's time stamp.

There are only about 5 log files on the disk in the GPSFILES directory which take up a total of about 2.5mb, so there is plenty of free space available. There is nothing else on the drive.

Hi. I bought a 3080 a few weeks ago and it works most of the time.... I have the current firmware with static navigation turned off. Now, this morning I turned it on for about an hour and so and walked around, took some photos with my camera and was able to sync them all up perfectly.

This afternoon, I turned on the 3080 again, waited for the green light to start flashing and then went out for a few hours. About 3 hours later I returned, having checked the green flashing light a few times to make sure it was still flashing (and thus 'happy!'). When I returned home I connected the 3080 to my computer and there was only a log file from this morning! Absolutely nothing was recorded onto the device this afternoon, even though the green light was happily flashing away and there was plenty of battery power.

Have other people experienced this problem at all? Any thoughts would be appreciated.

Thanks in advance.
gpspromeneur Posted - 01 nov. 2008 : 12:49:10
to keeshu

i vote for your requested feature : true multiplatform also for updating.
several month ago i contacted amod by mail at their site support to ask for this feature.

for example my kodak still camera is true multiplatfom for connecting (it uses standard as PTP and UMS protocol) and for updating (just copy the files in its memory, switch on, swith off, at each startup it checks if there is files for updating, in case yes it performs updating)

i never had any answer

resume: the firmware has the ability to make itself the updating. you don't need any software for updating
keeshu Posted - 08 oct. 2008 : 18:07:14
I also managed to update the AMOD on a colleague's PC where he had an administrator account, so indeed that seems to have been the problem. It would have saved me a lot of time and effort if the documentation had mentioned you need admin rights... It would also be nice if you didn't need a PC with Windows to do the update.

The user interface I can live with; there's not much you need it for anyway. Set it to the logging mode you want and it will remember that setting. Having to use three batteries is indeed a pain in the neck. However, a fixed battery with USB charger will not help you when you run out of juice in the middle of the Amazon rainforest... Fresh batteries will always work. I would prefer to have it run on two AA batteries, though.

What I don't like about the AMOD is the time it needs to sync to the satellites when just switched on. It sometimes takes more than five minutes to syncronize. That is way too long. I have to remember to switch it on before I leave the house. Also, the track is not very good in the city. When walking, according to the AMOD, I sometimes reach speeds of over 200 km/h, and distances will be all over the place. Very erratic sometimes. For geotagging your photos it's usually not too far off, but if you want to load your track in a mapping system it sure looks funny.

The documentation is written by people who know how it works for people who already know how it works; i.e. almost useless.

The tracks are written on the filesystem without a date; for a little black box that know exactly what time it is from the satellites this is strange. Also, the track files should have a suffix so programs can recognize their file type.

What I do like is the easy with which I can transfer the log file to my Mac. Other trackers I had before all used proprietary protocols and the software to load the tracks sucked. AMOD made it easy.

I convert the tracks with HoudahGPS (freeware) http://www.houdah.com/houdahGPS/ to a GPX file which in turn I feed into Trailrunner (shareware) http://trailrunnerx.com/ to see if the track makes any sense. If it does, I then feed the GPX file into GPSPhotoLinker (donationware) http://www.earlyinnovations.com/gpsphotolinker/ to do the actual phototagging. Works like a charm.

Changes I'd like to see:
* faster satellite sync
* better tracking
* smaller form factor
* two AA batteries
* better documentation
* platform independent updating
* file type suffix
* proper file dating

I just upgraded my amod agl 3080 without problem, I already upgraded it to 2.0 sn off a few months ago, now 2.2 sn off.
I just need to use the administrator account of my XP box.

I use the gps with my mac to geotag photo, no problem, last weekend I do 2 hours of car with the gps in the bottom of my bag under my legs and it keep track without problem.

The only bad stuff are :
- very very dry user interface, 2 buttons and you have to count the flashing led :)
- batteries, 3 (not 2 not 4), and 3 batteries will do a day, no more. I just buy a big charger for it and my flash batteries.

Next version, can you make it with a fix battery and a USB port charger ?
markx Posted - 09 sept. 2008 : 00:47:01
I have the same error when trying to update firmware. If the unit is not connected, it gives a "device not found" message. If the unit is connected, the program simply crashes and got shut down by Windows XP. Sigh.

I got it this morning, and so far has been pretty good. To me, the non-proprietary data format is the critical factor for getting this one. I really liked the design of Phototrackr, but the whole activation process required to get the data is just too Steve Jobs for me. I got it from gpscanada.com, because I don't like dealing with customs and brokage. The device is shipped with firmware 2.0, with SN on I believe. So far I'm using it for cycling, so it may not be as big a problem as walking. I'll post more reviews once I get more time to play with it.
keeshu Posted - 06 sept. 2008 : 09:40:48
I just hate it when manufacturers advertise their wares as 'platform agnostic' and then make the updaters available only for Windows (a platform I don't have, don't want but need in this case.) The whole idea of 'platform agnosticism' is that you can use it on other platforms than Windows.

I'm sure you could have updates happening by putting the update image on the device, touch a magic combination of buttons and have the image read to memory. No computer neccesary except to download the image and that you can do on any platform, as long as the website isn't built exclusively for Internet Explorer. I've seen that happen, too!
rlpatton Posted - 05 sept. 2008 : 22:06:21
Yes, that is probably it. Since my configured user on XP (home) has administrator privledges, these types of security issues frequently slip my mind. Yes, give it a go as a user that has admin rights.

Good luck.

@rlpatton: We actually used the USB-drive function of the AMOD to transfer the ZIP files from my Mac to the PC. When the zips were copied to drive C: and unzipped, the update gave the now infamous error.

Thinking the Mac had made a booboo transfering the zips we then downloaded the zips from the AMOD website. Unzipped those, ran the GoNoGo.exe: same error. Then downloaded the old v2.0 zip, unzipped and copied fwupdater.exe to the v2.2s directory. Ran the fwupdater.exe: same error.

So, to recapitulate: the AMOD is visible and reachable as drive G: named "GPS Tracker". All downloaded software gives a device error. The AMOD functions normally and I have no problems getting files on or off the USB-disk.

I'm starting to think in the direction of not having enough privileges on the PC. It is running Windows XP Pro and the user was NOT running as administrator.
rlpatton Posted - 05 sept. 2008 : 21:45:58
Hello,
Well, this seems to be a tough one. If the system is recongizing the unit I having difficulty finding a solution. But to answer your question. No, you do NOT need to run the update program from the unit. Running the program from the C drive should be fine. That is what I did. For some reason the program is not finding the unit. Lets make sure the system is really recongizing the unit. Navigate to the unit by clicking on "my computer" on the desk top. Then click (or double click) on the unit. My case the drive letter is R: (but yours most likely will be different). But the name should be "GPS tracker". After you click on the unit the window that displays should have a folder called "GPSFILES". If that all works then I don't have a clue and need to do more thinking. If it does NOT work, then you have a problem with the unit or PC. Give that a go, and let me know.
keeshu Posted - 05 sept. 2008 : 21:09:41
@rlpatton: I can't remember the exact error message, but it was something like "USB device not found" only it didn't say USB but something similar. UBC or UCB or something like that. The GPStracker was visible in the list of available drives as drive G:

@doug2311: I did download the v2.0 zip and extracted the fwupdater.exe from there. This is older than the GoNoGo.exe that comes with the v2.2(s) but has the same number of bytes. It failed too, with the same error message.

Does the upgrade work if you run the updater (whatever name it's got) from the hard drive of do you need to run it from the USB-disk in the AMOD? I ran it from the hard drive C:
doug2311 Posted - 05 sept. 2008 : 19:21:35
Previous firmware updates for the 3080 seemed to "usually" use fwupdate.exe. If I were you, I'd try the 2.2S firmware install with fwupdate.exe instead of GoNoGo.exe. I did notice that both 2.2 zip files (the original and the SN_off versions) didn't seem to include fwupdate.exe for some crazy reason, so you might need to get that out of the older 2.0 zip files instead.

What error did you receive. The unit will show up as a "device with removable storage" under "my computer". The drive letter will vary but the name of the device should be "GPS Tracker". If you don't have this, the system did not recongize the unit and the update application will fail.

@jaimev - thanks for the feedback, I generally use the Qstarz Q1000P thanks to the BT747 software that produces GMaps files out of the box, but I need to give the AMOD another chance ;-)

@tlc - how did you RMC vs GGA tests go ?
collinm Posted - 01 sept. 2008 : 21:18:38

jaimev Posted - 31 août 2008 : 07:11:13
First, many thanks to all the people who contributed to this topic. It helped make my choice of purchasing this unit quite easy.

I got my unit earlier this week from Semsons, and updated it to the latest available firmware (version 2.2 Static Navigation Off). As shipped, my unit appeared to have an earlier firmware version because pressing the Mark button did not produce a standard NMEA waypoint format in the log file - just the strange AMOD sentence. After the 2.2 firmware was installed, I got both the AMOD sentence and the NMEA waypoint sentence. I chose the SN off firmware version because I plan to use this unit primarily at walking speeds.

For curiosity, I decided to just let it collect data overnight while it sat on a window sill on an east facing window on the second floor of our house (see yellow dot on the left hand side of the picture below).

I put in some old rechargeable NiMh batteries. Using a La Cross BC-900 charger, the measured capacites were about 610 mAh, 750 mAh, 810 mAh. I used mode 1 to collect data every second. I was very surprised to get a total of 13 hours and 38 minutes of data considering the mediocre state of my batteries. File size was 13.2 Mb. It was nice that the unit could be mounted as a USB device, and files read off of it without the need to have any batteries in it.

Here's the scatter plot of the data. I used GPSBabel to take the NMEA log file and create a KML file which I uploaded to Google Earth. The accuracy is pretty much what I expected, compared with similar experiments done with older GPS receivers that I owned (Garmin GPS 12XL and GPS V).



I'm pleased with the sensitivity. Today, I had the unit strapped to my backpack, and our family drove to a train station, to catch a train to nearby city to attend a street fair. Once a fix was obtained, the unit never lost lock, even when it was inside our van, or on a moving train (I sat close to a window with the backpack at my feet).

I'm also pretty happy with how easy it is to geotag my photos. First I make sure I have time correctly set on my camera. I have a Canon SD800 digital camera, and I've set its time based on a Casio G shock watch which updates its time daily via the NIST WWVB signal that's based on an atomic clock. I run the Allbest CHDK firmware on the camera, to display time in seconds on the camera's display screen and confirm that the camera time and my watch time matches.

At the end of a day of shooting, I just take the NMEA log file from the AGL3080, amd then use GPSBabel (using command line mode under OS X via Terminal) to convert it to GPX format. Then I use GPSPhotoLinker in batch mode to geotag all the photos taken.
tlc Posted - 28 août 2008 : 07:05:14
Thanks, Doug.

I understand that RMC mode stores more points and runs longer on a set of batteries.
What I'm wondering is, what types of applications need the additional data in from
the GGA/etc. setting?

I don't want to get back from a trip, try some cool new app. and find out I needed
the other data. I assume that RMC is enough for photo tagging.

Anyway, I'll play it safe and use GGA/etc. for my first trip.
doug2311 Posted - 28 août 2008 : 05:12:58
@tlc - For information on what static navigation (SN) is, check here:

http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=25575

Basically, SN "snaps" the position in increments to decrease small bits of drift and wobble which makes for nice, smooth GPS tracks if you're driving in a car. When you're on foot, though, and meandering around a bit through a city or whatever, the track will look kind of jumpy and not be quite as accurate. Most of my own photography is done on foot so I use the SN=OFF firmware, but I'm a bit of a geek who loves playing around with this stuff. Even if you use the default SN=ON firmware, your photos will still come out pretty darn accurately tagged so don't worry about it much.

As for the RMC vs. GGA stuff, the only time you'll need to consider changing any of that is if you plan on trying to cram LOTS of data in your device without downloading it. If you turn off everything but RMC and only tell it to save a data point only every 10 secs, you can store 4 months of continuous data in the 3080 (not counting the time the unit is off while you're changing batteries every 10 hours!). The only time you'd need that is if you plan on taking a 4 month safari where you don't bring a laptop but do bring about 864 AAA batteries. :-) The default mode gives you 72 continuous hours (7+ battery changes) which is enough for most stuff I've done, though I did put it into one of the longer lasting modes for a two week trip I did a couple months ago. From a technical standpoint, RMC gives you position, velocity, and time data points whereas GGA I believe only gives you position and time data, which means your mapping/tagging software has to compute velocity from knowing the elapsed time and change in distance between two data points.

As for Mac OS X software, I highly recommend using GPSBabel (for converting NMEA to .gpx for photo tagging and .kml for GoogleEarth) followed GPSPhotoLinker (for adding tags to photos based on .gpx files). They've worked great for me.

Now I don't have any idea what DPMB,5,0 is supposed to stand for but it isn't a standard waypoint marker and so none of the log conversion software that I know of is looking for it.



The new firmware version 2.2 repairs the waypoint marker function issue. This is the quote from the firmware release note:
"=> Add support standard $GPWPL NMEA format, and still keep our position mark $ADPMB format"

FYI,

v2.2, dated 8/12/2008, is on the website, http://www.amod.com.tw/Support/download.asp?tLGIqc6FuoJI , in both SN=on and SN=off versions.

I haven't tried either yet. I've just gotten my 3080 and I'm trying to understand the SN decision and which mode I want before a trip Friday.

I want to tag photos, using OS X or Linux, then do google-maps-type-stuff with them. Should I use RMC or GGA/blah ? Should I use SN=on or off?

Thanks,
tlc

It's been a few weeks since I first owned this product and so far it's working very well at what it does.. logging my movements via GPS. I never did upgrade the FW to "fix" the static navigation issue (yet). So far it has not been a problem (according to the accurate maps I've made in Google Maps and Google Earth). These include both walking and driving. As long as I give the device time to "lock-in" after turning it on, it's tracking very accurately.

I actually haven't even used it for it's intended purpose yet (geo-tagging) photos. I tried briefly to have an experiment but the JetPhoto Studio software app has issues with the WXGA+ 1680x1050 screen on my laptop and refuses to even open unless I choose a different "higher" resolution and use 96DPI fonts... This is not going to work clearly so I will need to find other software to meet those needs when I get time to work the issue thru.

I agree with the User Interface comments a couple posts above regarding the lights and the bass-ackwards way the LED's flash when tracking. And the convoluted system of lights and codes and button presses required to make changes to the settings and update firmware etc are not for the feint hearted, or those exhibiting anything less than Rain Man abilities to memorise these things.

I believe I have solved this issue easily, simply and without making any changes to the hardware. The idea just came to me a few minutes ago as I sat here, with my 3080 plugged into my computer offloading todays GPS logs... And also after spending the last day and half installing and setting up a new ADSL2+/router/modem/Wifi/VoIP device... Just build a web-browser user interface the same way we log into our routers that also have no screens and just a series of lights. You can log into the "guts" of your router and administer it's many many complex options and menus and settings from the comfort of your web browser. Then flash these changes to the device. How easy would THAT be. Imagine logging onto a browser based UI for the 3080 that lets you do SO much more than is possible with the current system of changing settings and logging modes etc.

I realise that routers have IP addresses and USB devices do not. But I just figured that since we are all plugging these things into the computer anyway to get files off (one of it's big selling points IMO) that there must be an easy way to allow users some kind of browser based, GUI access to change the settings and do other admin and users tasks on the device.

Heck, if I was smarter I would try doing it myself.

During a week I recorded ten tracks using the Mode 3 (= 5 secs intervals) with freshly recharged Eneloops (969, 978, 996 mAh). The total recorded time was 14h 25min (plus approx. one hour spent with searching the satellites) until the complete exhaustion of batteries.
All tracks were made in the city, often with a poor reception.

The battery life and number of batteries is my one of my minor complaints about the Amod device. I used some brand new 1000 mA-h NiMH AAA batteries on my trip and usually got somewhere near the advertised 12+ hours of life, but that battery time did seem to go down a decent bit on days when I spent a lot of time in indoor areas (museums, etc.) where the GPS lost signal and therefore went into search mode. My guess is that search takes up about twice as much juice or more than normal operation. Also, using 3 batteries is a bit inconvenient since my battery charger can charge either 2 or 4 at the same time, but not 3. So, yes, 2 AA batteries would have been a more convenient design than 3 AAA and the battery life could have been even longer with 2 AA.

The other minor complaint I have is how the green LED on the Amod blinks when locked on a signal, but is solid green for when searching. To me, that's backwards from a UI standpoint. To me, blinking should indicate "pay attention to me", whereas solid should say "all is good". Moreover, I would prefer that the Amod had a "stealth" mode where it could run with no LEDs showing at all--I wound up just covering the LEDs with black tape most of the time so no one (in the security/terrorism paranoid world we live in) would even notice it.

All in all, these are all just minor nits. Overall, I found the 3080 to be a solid product and well worth my $70. The sheer number of datapoints it can collect is pretty staggering and it was really one of the few devices that would let me travel and collect weeks of GPS data without once needing to go near a computer.

@lochness - no, SN is set by the firmware, at least for now. Don't worry though it should work fine in your car too, you'll have more "wandering" but that doesn't make the readings more inaccurate than the "SN Frozen" position.
doug2311 Posted - 21 juin 2008 : 00:18:09
I bought the Amod 3080 from Semson's right before my recent vacation to Europe, changed out the firmware based on the helpful instructions in this forum to SN=OFF, and happily spent two weeks wandering around Europe. I was thoroughly impressed with this little unit and it did pretty well both outside and even surprisingly well inside some buildings. With the recording mode changed over to just every 10 secs vs. every second, I was easily able to get the full two weeks of data without needing to ever empty it out on a computer. After I got back, I again followed the advice from this forum on using GPSBabel and GPSPhotoLinker (Mac) and in no time my photos were all geotagged and sitting on Flickr to impress my friends and family.

Anyway, I just want to say a big THANK YOU to all the various posters and experts who've provided advice on this forum. You made it all seem so easy! :-)

lochness Posted - 20 juin 2008 : 12:33:46
I just purchased one of these this week and it's the V2.0 (SN = ON). So far I have only had a chance to test it by driving to and from work in the car. And the mapping it did was near perfect when view in Google Maps/Earth against the roads I travelled on, within 2-4m of actual along the whole 52km journey :)

However I believe that if I leave SN turned on, that when I start to use this unit for it's intended purpose (geotagging my photos I take walking around on foot) that having SN=ON will cause inaccuracies in the GPS data.

I found the firmware upgrade at AMOD and am about to install it, but I was wondering... Is it a one-way process ? ie: once I install V2.0s to turn SN=OFF then I assume if I use the AGL-3080 in the car, I will now get funny readings. But those on foot, walking around will be "good".

Is there any (simple) way to turn the static navigation "feature" ON/OFF without having to replace firmware versions ?
Would be handy to be able to accurately track my drive TO the photo site in the car, then accurately log my photos taken on foot, then accurately track my drive home again.

Thanks... (I bought this unit largely based on my readings here in these forums. I'm liking it so far. much smaller than i thought)

trs2004 Posted - 19 juin 2008 : 05:45:00
During a recent trip, my little AMOD 3080 dutifully recorded my locations. Every evening I would check my progress with JetPhoto Log Manager, using it to display the days tracks in Google Earth. Then I would save the data as a GPX file.

Now when I try to tag all of the pictures made during the trip, I find that AMOD GPS Photo Tracker 1.3.7 doesn't read GPX files.

Is there a way to convert the GPX files back to log files that AMOD GPS Photo Tracker 1.3.7 can read?
gpspassion Posted - 11 juin 2008 : 01:54:21
Thanks for the input, the "post-it" theory makes sense.
robertlipe Posted - 09 juin 2008 : 18:10:18
That's just one of many puzzlements on this. There is no NMEA checksum and no actual data that's clearly associated with it. It appears to always come before the GPRMC, but I've looked at only a small sample of these. I haven't looked to see if it actually creates another entry (i.e. you'd want to treat that GPRMC as a unique waypoint and not place it on the track list) or if it's just a post-it stuck on a normal trackpoint (i.e. you'd want to duplicate that trackpoint and create a waypoint from it).

It really stands out as an oddity as it doesn't use the normal proprietary "$PVENCMD" format, doesn't have the checksum, and I don't know what the "5,0" is.


Oh, and contacting Pierre is helpful, but a bit redundant; HoudahGPS uses GPSBabel as the underlying engine for this kind of thing, I'm pretty sure.
gpspassion Posted - 08 juin 2008 : 03:07:52
Interesting thanks, where is the actual position shown, immediately after the DPMB ?

I am sorry to reply to this question so late but I just recently purchased an AGL-3080 and was having the same problem myself.

It looks like the AGL-3080 is using a non-standard NMEA string to mark a waypoint using the Mark button on the side of the unit.

Here is a couple of log entries from mine:

$GPGSA,A,3,14,03,21,31,,,,,,,,,9.0,5.9,6.8*3E
$GPGSV,3,1,10,14,84,273,24,03,26,239,16,21,19,137,18,31,13,176,22*7C
$GPGSV,3,2,10,22,61,034,22,19,33,275,25,18,29,074,21,06,26,224,*72
$GPGSV,3,3,10,09,19,048,17,32,17,282,*7C
$ADPMB,5,0 <--- Here is the button press!
$GPRMC,162202.511,A,3510.3071,N,11358.6823,W,0.90,24.52,070608,,,A*4E

Now I don't have any idea what DPMB,5,0 is supposed to stand for but it isn't a standard waypoint marker and so none of the log conversion software that I know of is looking for it.

I have contacted the author of GPSbabel and he said he would include a fix to convert this to a normal waypoint in the next version. I will contact the author of HoudahGPS and let him know as well so he can fix it too.

If you write software to read/convert gps logs you might want to be aware of this quirk on the AGL-3080.

I hope this info is helpful to someone!

1. i have just got an amod agl3080 from semson via amazon usa.
Very fast shipping :
- purchase date 30 may 2008
- in my letterbox(France) 4 june 2008
- total cost 66 E

2. 2 problems
2.1. unable to upgrade to 2.0s with Linux

i thank in adavance anyone who sends this message to amod
to help Amod supporting Linux and others OS

i send this message to amod :
**************************************************************
Oject : AGL3080 firmware upgrade for linux

i can't upgrade the firmware with linux. I have only linux

i suggest to you :
adopt the kodak method for its DSC which is a sole solution independent of OS

what is the kodak method ?
you copy new files to the disk area
then
you restart the DSC
then
DSC boot
then
DSC search for new files
then
DSC upgrades

This solution is independant of the today OS but also of the past and future OS

Thank you in advance
*********************************************************************

2.2. knowing if your firmware is 2.0 or 2.0s

Amod says :
*********************************************************************
3. This "V2.0" vesion is default for AGL3080 device.

The default value of this device is with Static Navigation(SN) "ON".

The other version "V2.0S" is with Static Navigation(SN) "OFF".

=> How to identify from two different versions?

If it's default version (V2.0), Storage LED will flash "twice" after all three LEDs are

on and then off. The GPS LED will start blinking when the device starts tracking successfully.

If it's "SN OFF" version (V2.0S), Storage LED will flash "three times" after all three LEDs are

on and then off. he GPS LED will start flashing when the device starts tracking successfully.
***********************************************************************

i can't count if there is 2 or 3 flashes

it would be a good thing if in the data log the system writes the exact version number
magrolino Posted - 29 mai 2008 : 19:29:43
I would be interested how well the device works now with the upgraded firmware: how long do the batteries last with set to 5 secs interval or even 10 secs? As I work on mac it is one of the few devices I can go for; I thought about waiting for the "new" apt photofinder which should come out soon (as I read) but I read a lot good feedback about the AGL3080.

thanks for your feedback in advance!

tholin Posted - 29 mai 2008 : 19:23:46
I got a 3080 yesterday and today I took it for a walk. I uploaded the log here if anyone is interested:
http://www.cyd.liu.se/~tholi945/GPS_20080529_133522.log

The conclusions I can draw is, if you have less than 6 satellites in view the path will be wobbly and it takes a while (25 min this time) to get more than 6 satellites. Once you do get more satellites the path is dead on. Static navigation was off.

I also came to the conclusion that walking 8 km makes my legs hurt.

I have the same picture in the AMOD GPS Photo Tracker (v. 1.3.5, 1.3.7). If you try to maximally zoom out map view, you can see the world map is located in the "south".

The program apparently does not work well. My imported GPS logs also show still the same start and end times 0001/01/01 02:00:00...
It seems to me, the program worked well in the beginning (maybe it was changed after the SP1 update installation).
Fortunately, there are some good alternative programs available. I use Route Converter, locr, GeoSetter and DGManager.

Your output data sample shows you selected the Mode 2 format in setup (only RMC->1sec). This mode does not record the altitude. If you want to obtain altitude data, switch the AMOD setting to Mode 1 (or 3 and 5, resp.).

Sorry for the delay. You need a device that support OTG, eg.: external hard drive case. See my previous posts for details. Once you have the device it quite obvious how to copy files from GPS to external storage.

wavshrdr Posted - 24 avr. 2008 : 05:35:52
Anyone know of an easy way to get the AMOD in sync with a camera? Is there a way to access the internal clock of the GPS on the AMOD so I can make sure the times are in sync for both devices? I tried exporting a log while marking a waypoint and it always seems I am off from a few seconds to a lot more than that. Any advice?
wavshrdr Posted - 20 avr. 2008 : 03:34:42
I did some extensive testing today while riding my Xootr push scooter. I went on about a 5+ km trek around an urban area. I don't know how to post a track on here so show you the results but I am quite satisfied with them. My average was about 13km/h and max speed about 29km/h. The AMOD did an excellent job with my track.

Considering that the accuracy can be degraded at any time, my track was never off by more than about 1.5 meters. 95% of the time though it had me EXACTLY where I went with my scooter. I was staying to the bike paths for a lot of my route and they were denoted by white lines 1 meter apart. It showed me consistently always between them. I had it suspended from the collar on my jacket and it had no issues picking up a signal even while bouncing around as I kicked the scooter.

This thing is definitely a keeper for me. Add a little LCD, BT and make it usable via a USB cable as well and it would be tough to beat. I love the fact it takes normal AAA batteries and has given me about 13 hours or so real usage on Sanyo Eneloop batteries. These batteries are awesome as they don't self-discharge near as quickly as normal NiMH batteries do. So even if I don't use them for a month, they still have a good charge on them while my other ones will be most likely flat.
TonyW. Posted - 17 avr. 2008 : 18:23:32
That would certainly be another nice feature.I'm wondering if that could be done through software ?
wavshrdr Posted - 16 avr. 2008 : 19:57:44
I just bought a new AMOD from Semsons. It came pre-loaded with the new firmware. So far my testing of it looks pretty good. Acquisition times are very good as well. The new modes are really useful. I'll be trying them all out. I only wish this thing was usable via a USB cable to use as a GPS for on of my laptops as well.

trs2004 Posted - 16 mars 2008 : 19:36:36
Here is my latest test track. The same route as before but this time using mode 1 from the SNoff patch.


1. A wild spike when the unit found itself after a cold start.
2. Wandering for a bit on the wrong side of the street.
3. Still a few problems at this corner but then continues correctly, even under the train bridge.
4 and 5. Wrong side of the street
6. The corner is almost correct but then continues on the wrong side of the street.

Of the three modes I tried in a pedestrian setting, I found that mode 5 @10 sec gave the best results. In my case, more is definitely not better. Since I don't plan on taking many pictures from a moving platform, the longer time between data points will not be an issue. I will most likely be standing still for at least 10 seconds while composing my next picture.



gpspassion Posted - 15 mars 2008 : 14:42:35
Thanks for sharing your tracks, yes the problems you're seeing seem pretty "standard" to me, they are in areas where multipath (bounced signals) could kick in and at low speeds GPS algorithms can't cancel them out easily. The ways to improve that would be using a large choke-ring antenna mounted on a pole ;-) Just one thing, in the extract you quoted above I'm referring to the general update rate, the logging update rate doesn't come into play, the unit just records what the GPS module outputs, there is no tweaking done at that level.

On another matter I just got rechargeabl 1000mAh NiMH AAA batteries to operate the 3080, I'll see what kind of battery life I am getting.
trs2004 Posted - 14 mars 2008 : 23:53:05
After resetting to mode 5, I went to walk the same path with the unit again in an outer pocket of my jacket. Here is the result.



1. There still seems to be a problem at this corner.
2. The sideways jog appears where I went under a train bridge. All of the steel seems to have confused the unit.

As for the rest of the track, the AMOD AGL 3080 did a very good job of tracing my path, accurately showing where I crossed the street. After reading the links provided by gpspassion, I have a better understanding what the built-in limitations of GPS units are. Today's results have renewed my faith in this unit.

As a final test, I will have to retrace the route in mode 1 to see how much of a difference SNoff makes compared to the original configuration.
trs2004 Posted - 14 mars 2008 : 01:02:54
Thanks for those links. Now I know a bit more about what would be considered normal for a GPS. I especially like the part where
quote:
GPS system's natural "inaccuracy" of approximately 10 meters. While this inaccuracy is easy enough to "rub out" with a properly tuned firmware inside the receiver in driving conditions (60 kph is 17 meters/second) that you can predict to some extent, it's much more difficult if you're walking at 5 kph or 1.4 m/s, well below the accuracy of GPS each second. It's unlikely that much can ever be done to fix this latter aspect ...

Since I was testing in mode 3, @5 sec I was still under the 10m threshold. I'll have to try it in mode 5 @10sec instead which should put me over that point, around 14m

No this is quite typical for a GPS unit, indoor accuracy and at low speed is a known problem, I'm pretty sure I've already given these link in the topic but here they are again -> http://www.gpspassion.com/fr/articles.asp?id=143&page=6 and http://www.gpspassion.com/fr/articles.asp?id=143&page=5 and there are many others in the in depth articles on the portal.

Just how accurate should a GPS track be?

After applying the patch for SNoff, I tried the windowsill test again. The result were a bit better than before, with most of the wandering inside a 12m radius. How does this compare with other models?


Next I went for a walk. Once I got a fix, I put the unit in an outside pocket of my coat where it stayed for the whole trip.

Anomalies
1. The GPS track starts about 144m NE from where I was standing while waiting for a fix. This might be a spurious data point during startup
2. The GPS track shows me back-tracking about 70m
3. The GPS track shows me taking a 160m detour to the far end of a parking lot but doesn't show that I crossed the street at the corner.
4. The GPS track shows me crossing the street and then returning after 12m.
5. The GPS track shows me on the wrong side of the street for 90m. This is open sky without any buildings nearby.
6. The GPS track again shows me crossing the street and returning

This walk was done with the unit in mode 3. I'll have to try it again in mode 1 to see if more frequent sampling will improve or degrade the track.

For general location and just to help remind me where I went, it might be acceptable but if I really need to know my actual path on a trip, I think I might have to look elsewhere. Too bad since it had so much going for it, driverless, easy to use.

Am I expecting too much from this class of GPS logger? Will I be just as disappointed by other models?

Ah it keeps getting better, thanks for sharing the good OTB news, I really need to get a hold of a miniUSB to female USB cable now !

I was skeptical when I heard about incoming update of firmware. I own many devices for which vendors promised upgrades and fixes and rarely they keep their word. That is why I am very happy to announce that new firmware 2.0s for AGL3080 is fixing OTG issue. In other words I am able to copy files directly from GPS to harddrive without use of the computer (please read my previous posts for details). Great work AMOD, thanks Gpspassion for help.

Hehe, that was just a suggestion I made and they followed up on it ;-)

GGA/GSA/RMC and VTG are all NMEA messages, you can read about that here http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=5214 - to summarize it's the data sent by a GPS receiver to the receiver, the fewer the messages the more you can store, RMC is generally enough for picture geocoding, with www.Locr.com for instance, but it you want full navigation information you will need the GGA/GSA/RMC/VTG combo.

Great! I just downloaded the new firmware, but I don't know what "GGA/GSA/RMC/VTG" means, can anybody help me so I can setup the device?

With this update AMOD AGL3080 has become in a much better GPS device, the option to choose the update interval was a must-have for this device. Logging while walking used to retrieve jumping coordinates, I think now it will me more accurate. NOW I'm so happy with my purchase. Thanks AMOD and GPSPASSION!

I wrote a little script to automate the NMEA to KML process in gpsbabel, details here http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=108370

Downloaded and will install it soon. While there, I also noticed another new file "AGL3080_V2.0_Original.zip" Should it also be installed first, it being V2.0 while the "AGL3080_V2.0S_SNOff.zip" is V2.0S? OR is it a way to reverse the change?

Edit. After reading the Release notes, the two files are complimentary, for either SN on or Off.

Edit 2
Also had a smooth upgrade. Now it is sitting on my windowsill for an other overnight static test.

UPDATE ON SN : Looks like the new firmware I was told about is available here : http://www.amod.com.tw/Support/support.htm - it's called "Firmware upgrade for AMOD GPS Photo Tracker for SN off"

Downloaded and installed without a hitch !

The release notes also mention a new "SETUP MODE" with 6 logging modes with update rates of 1/5/10 seconds. One thing they don't say is that once you have set the mode you want you have to press the power button for 5+ seconds to get back to register the setting and turn off the device.

In Mode 6 (RMC 10 seconds) you can log for a hefty 2880 hours or 120 days !
