Qstarz have just launched the Q1000X Bluetooth GPS datalogger based on the new MTK v2 (MTK 3329) GPS chipset rated at -165dBm and previously used on the Qstarz Nano BT-Q1300 Bluetooth datalogger.

While the Q1000X uses the solid design that we discovered in 2006 on the iBlue 737 it is the first GPS datalogger, with its cousin the iBlue 747A+, to offer AGPS assistance for faster GPS acquisition. It is of the Internet AGPS variety with a file good for seven days being downloaded over the internet and then uploaded to the device. This should be especially useful for a datalogger that tends to get placed in difficult areas like backpack pockets.

A test unit of the Qstarz Q1000X has already made it to the "GpsPasSion Labs" and been subjected to some first test runs, so stay tuned for some comments.

Questions, comments ?

This looks like a solid device, thought about the 1300, but seems it's struggling some with reception. If this performs, it'll be on the top of my list. Waiting for more details.

Is the following behavior the same as Q1000?

NAV : BT-Q1000P can be used to navigate with handheld devices (PDA / Smartphone / Laptop.), but the data log function is disabled.

LOG : BT-Q1000P only can be used to record your travel path, and navigation function is enabled.

http://www.qstarz.com/FAQ_BT-Q1000P.htm


Moreover, can ephemeris data be dropped from SmartPhone by using this?

No MAC here so can't help with that part sorry.

Have completed some preliminary Globalsat BT335/Q1000P/Q1000X testing and can't say I really see any big difference between the Q1000P and the Q1000X, in fact the Q1000X struggled to reacquire the fix after getting out of a tunnel in the train the other day, as seen below :



I have some pedestrian testing in town I need to analyze.

@unyaten - that FAQ on the Qstarz site is wrong at least as far as my Q1000P is concerned, NAV=BT/USB Nav and LOG=LOG+NAV USB/BT. I verified that the Q1000X behaves similarly. The behavior they describe was for the old Q1000 (non P). The only constraint is that you'll have to be in NAV mode to do the initial pairing.

Problem updating AGPS data : Others have reported this problem with the 747A+, I'm also not able to use the AGPS utility with the Qstarz Q1000X, all I get is this screen below. I'll ask for a new version.

Qstarz have added the AGPS feature to the V4.3 of their software available on their site for download. I was able to verify that it works fine, need to test its efficiency now.

Did a comparison in town on foot the other day between the Qstarz Q1000x/MTKII and Globalsat GH-615Watch/SiRFstarIII and it didn't do very well, more "noise" in the track and also some significant multipath problem at some times, Q1000x in blue, GH615 in red :

I don't have a problem updating A-GPS, but I don't get streaming GPS messages either. Same problem in QstarzGpsView v1.2.215.

Sometimes it does "something" when you switch the connection off and on a few times.

I do have a problem with logging at a frequency that I desire. For some reason it always defaults back to 5 second intervals when I switch the slider to "Log". Even if I set it before to 5hz. If I set it on 5Hz AFTER I started the logging it works fine from then on. When I switch the slider back and forth, it's back to 5 secs again.

Is there some way to make this setting more permanent?

Yes, use BT747 http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=85368 ;-)

Like I said, AGPS works fine with v4.3 of the Travel Recorder available on their site.

That's what I used. I tried the "5Hz easy setting", doing it myself manually on the ctrl tab and I tried the same using the QstarzGpsView software that Qstarz gave with the GPS. Whatever I do, it logs fine at 5Hz just after I set the frequency, but when I switch away from LOG and then back again, it resets to 5 sec logging.

I want to use this device on a ski trip so I want it on 5Hz automatically every time I switch it on.

Indeed, but it also works fine for me from QstarzGpsView v1.2.14 and QstarzGpsView v1.2.15 where you stated that it didn't work for you. I click on to start the connection, then Update on the AGPS button and it runs for a while until it's done.

Good for you it seems (Qstarz)GpsView has an issue with most computers our there, XP only maybe. Anyway no longer a problem since Qstarz have AGPS taken care of in.

If you have questions on BT747 use its topic, the author monitors it closely. Maybe the log button makes the old trick unworkable though.

NO NEED TO QUOTE A MESSAGE DIRECTLY ABOVE YOURS, MAKES THE FORUMS EASIER TO READ, THANKS ;-) GPSPASSION TEAM
It's a characteristic of the device itself. It doesn't work with any software (Travel Recorder utility 4.3, BT747, MtkDLut109, QstarzGpsView v1.2.15)

I did some more checking and found that when I set the log settings too low, it defaults back to some default setting.

The minimum settings are:
Time 1.0s
Speed 10.0km/h
Distance 10.0m

If I set the Speed or Distance lower than 10 it defaults to "no logging". If I set the Time to less than a second it defaults to 5 seconds.

The fix speed itself remains at 200ms though, so maybe it would work since if I move less than 10 meter I don't need a log record either.

This is with all software including the log reader/mapping utility that comes with the unit.

For instance from MtkDLut109.

This is what I set (log per 0.2s or per 9 meters or when above 9 km/h)


When I switch off the device, switch it back to LOG and restart MtkDLut I get:


Is this normal behavior?

My firmware version is (from $PMTK705,) AXN_1.0-B_1.3_C01,0001,QST1000,1.0*6F

That's not the way you would set it to log at >1Hz, we have a speficic topic about that, you'll find it with a quick search and if memory serves it is linked from the first message of the BT747 topic.

Actually in that thread (and in the manual) it exactly says to set it like I did:

quote:
5Hz logging.
Set the following to enable this:
Time=0.2 s
Fix= 200 ms


quote:
“Time”
The time period at which GPS data will be logged (if active). For example, a value of 8 will log GPS data every
8 seconds.
The time period can be fractional. A value of ‘0.2’ will log the data every 200 ms. That would correspond to a
frequency of 5Hz. If the fix frequency is also 5Hz, then you have 5Hz logging


quote:
“5Hz fix + log”
Sets 5Hz fixing and logging by the click of one button. You can observe the changes in the ‘control’ tab.


I just think MtkDLut works better since BT747 is displaying a lot of settings wrong. For instance what to do when memory is full and SBAS usage do not match with what the Qstarz utility shows and MtkDLut does match.

Anyway, I'm not simply talking about 5Hz logging. The problem is that it defaults the settings if the logging is set on intervals less than 1sec, 10 meters or 10km/h. Every parameter seems to have a minimum setting.

Just try it yourself in the standard Qstarz program (or whatever since it all gives the same results). Set logging to 5 meter. Switch off the GPS, switch it back on to LOG and see what the settings are from the software again.

The question is if that is normal behavior? I mean, it might be that these are simply the lowest settings since setting them lower makes no sense, but I would say it's more like a bug in the firmware.

Besides, I did get it to log at 5Hz, but only if I move more than 10 meters or faster than 10km/h. (fix time is 200ms, time=1, speed=10 and distance=10)

Anyone else with this type of GPS already who can try this and check their firmware version?

Yes that's what's explained in the thread I referred you to, you need a trigger, we'd been using speed. You should read it more closely.

So it's normal that you cannot set autologging for speeds under 10km/h? If so then why doesn't the Qstarz software limit this input?

BTW I went through the whole 32 page thread about the BT747 and it doesn't say anywhere that only a speed or distance trigger will work to get 5Hz. Only a question from you how to set a speed trigger. In fact it literally says that the Easy 5Hz+log button sets the log time to 0.2 seconds and the fix to 200ms. Which indeed it does.

That's not the topic you want, the topic you want is the one linked from the first message BT747 topic in the "To log data to the internal memory at >1Hz" paragraph and called "[GUIDE] Logging GPS at > 1Hz with a datalogger".

As for the Q1000X not working as per the manual, take up that issue with Qstarz, nothing we can do about that here. As you can see above with the unyaten's question about NAV/LOG selection, Qstarz don't always know in detail how their products work, or maybe the features were changed since the site/manual was written, hence the whole point of forums like these where we leave no stone unturned.

Don't double post, please...my answer again, depends on what your goal is, but you can log raw NMEA data with a freeware like VisualGPSCE, we have a dedicated topic to working with receivers at >1Hz : http://www.gpspassion.com/FORUMSEN/topic.asp?TOPIC_ID=76813

Please visit Qstarz's site for the revised and updated version of QstarzGpsView utility v1.2.17
Now, it connects to BT-Q1000X without a problem and also updates A-GPS data perfectly.
For your info..

If something is not working well in BT747, I'ld like to understand what so that I can fix it. This description is not precise enough however to know what to fix...

I wanted to report the issues in the BT747 thread, but I first tried the newer "autoupdate" version and that one works fine. So I assumed the problems were fixed already and the older version on Sourceforge would get updated someday and left it at that.

The "log full" setting was simply flipped (said "overwrite" when I had it on "stop when full" and vice versa)

The problem with DGPS I wasn't sure who was wrong, but I got different results from different programs there too. Turns out it was actually a problem in the QstarzGPSView software. It said DGPS was disabled when BT747 said it was on SBAS. Since the "log full" setting was clearly wrong in BT747, I (wrongly) assumed BT747 might be incorrect on the DGPS one too. The new version 1.2.17 now agrees with BT747 though.

Anyway, it works fine in the new version, but maybe you should renew the Sourceforge version or remove it there and point to the new site?

Hi Patrick
Thanks. I remember a problem with the overwrite indication.

I did not release the latest version yet because I want to make the interface a bit cleaner regarding the tagging functionality + make sure the translations are stable enough.

But if you think it is ok to make it official 'as-is', I'll not be as demanding.

Well the Sourceforge version is from october and it misses a lot of new features. On the other hand, people can simply get the latest (beta) version too so it's not a big deal.

Still waiting for gpspassion's q1000p vs. q1000x comparison. Which one should i go for? I don't care about TTFF, so the lack of AGPS does not matter. Battery life is more than sufficient with both. Memory equals.
Accuracy and reacquisition time will count, but which one is the winner?

Larger, standard 25x25mm vs, a 19.5x14.5mm like on the Q1200 or more likely the 18x18mm as on the Q12000 ultra - as you will see in the Q1300 review on the portal performance is good.

For those that are interested in such things, I have here some data from
QSTARZ BT-1000P Flash 1C20161C (EON,4MB) Model 0005 FW B-core_1.1 Logger SW V1.38
and
QSTARZ BT-1000X Flash 1C20161C (EON,4MB) Model 0003 FW AXN_1.0-B_1.3_C01 Logger SW V1.39
collected with the devices side-by side.
Basically, I turned on all logging options (including per-satellite SNR), stuffed both devices into one pocket, and took the train / walked around a city block for a few minutes. Maybe you can use this to assess device quality or sensitivity, I would certainly be interested in hearing about any findings.

I played with the 1000X some more, and there seem some changes as compared to the 1000P:

1) Neither BT747 nor 'Travel Recorder Utility V3' can turn logging on and off. Logging is only controlled by the switch at the side of the device, not by software.

2) The bluetooth light is always-on in NAV mode, and always-off in LOG mode. However, the device is discoverable in both modes (and on all the time, it does not seem to turn off after a minute or so). Once a PC associates with the device, the blue light will blink.

[Edit: mdeweerd states 1) more precisely below.]

To elaborate a bit, following exchanges with gec.

1) The SW does turn the logging off, but just a few instants later the device turns it back on. [the device first says the logging is off and on a slightly later status request, it says that logging is on].

Greetings,

I've decided to buy a GPS data logger, and my choice is set: I'll buy either an Amod AGL3080 or a Qstarz Q1000X.

There is only one detail that would help me in making a final decision.

Is it possible to det Q1000X parameters so that its recording frequency changes on the fly, depending on current speed.

I want to go on a 1 week trip, where I'll have no access to a PC to modulate this frequency, as it is explained in the manual

It seems, from the manual, that it is only possible to set a single frequency (custom/walk/cycling/car) and you have to stay with it until next PC connexion/

I would like to set a speed limit: when I move under this limit, Q1000X recording is made every 10 seconds and switchies automatically to 1s when above this limit.

Is the Q1000X able to do that?
If not, I'll buy the Amod [ED - SEE PM]

When you set the log condition for time to 10 seconds ans the log condition for speed then what will happen is that the device will log at least one position every 10 seconds and a position for every fix the speed is above the limit. The fix period is set differently and can be as small as 200ms, but is 1s by default so that would log a position every second when above the speed limit and five positions every second if you set the fix period to 200ms.

Another option is not to use the 10 second trigger, but to set a distance trigger. That way when you are standing still even for an hour, there is not additional logging.

I have logging set on speed for 10km/h and for 30 meters distance. If either condition is triggered, logging is enabled.

Which is why I personally use 10meters for the distance and 5 km/h for speed. If you walk slower than that, it can be set to 3 km/h.

Trouble is that the Q1000X has a minimum for each of the triggers. The minimum settings are:
Time 1.0s
Speed 10.0km/h
Distance 10.0m

Use a value below that and weird behavior can occur. For instance it might work for a while, but after switching the device off and back on, the trigger will have reverted to default.

10 meters distance should be accurate enough though. Personally I'm fine with 30m. I'm not drawing maps or anything. I just want to see where I went.

With BT747 and the same device (unless the device limits this, but that should not be the case) the minimum settings are:
Time 0.2 seconds
Speed 1 km/h
Distance 0. m

It would be possible to set speed resolution to 0.1 km/h but I did not think that there was a need for that.

Yeah it was quite confusing. The Q1000X actually lets you set the values that you mention for the BT747. It even works just after you set them, but after a while (after resetting the device) the values get reset to default (which basically means that the trigger is removed)

It's quite bizar (and annoying). I have no idea why it does that. It would make sense if there actually was a minimum setting and that it wouldn't work if it's set lower. Instead it DOES work, but then during a reset the value is deemed "illegal" and removed.

I'd say it's a bug to be honest.

The 'official' desktop SW surely 'resets' these values to values that that SW allows you to set - I do not think that this occurs when you stick with BT747.

The value gets reset when the device is reset (switched off and back on). The software used doesn't matter.

Still, I just tried it again.

Set distance to 5. Clicked Set and the BT747 screen shows 5.0. Then I switch off the Q1000X, switch it back on, connect BT747 and distance trigger is empty. It keeps working as long as the device stays on though.

If I do the same with 25 it stays. Any value under 10 gets reset to default (which is empty for the distance trigger) when the device is reset.

Trust me, there is a bug in the firmware. It really won't hold values under the ones I mentioned above.

Haven't been able to find a new version, but maybe newer models come with something better. My Q1000X has firmware AXN_1.0-B_1.3_C01(QST1000).

Problem with 2,5 km deviation of the track.
Look a snapshot of the map with tracks:
http://vadimat.users.photofile.ru/photo/vadimat/115475051/xlarge/131171774.jpg
Red color - part of actual track recorded with Garmin
Blue color - part of the track recorded with Qstarz BT-Q1000X. This track is false, large jumps in the blue color track are corresponding to the satellites loss.
Distance between waypoints 1 and 2 with the same time stamp is 2,5 km.

I'm using Qstarz bt-q1000x for a week and tried to record a 24-hours track, while from time to time using navigation via Bluetooth on my PDA.

Troubles started after approximately 18 hours of recording, the connection with BT-Q1000X was lost. I switched BT-Q1000X off and on and done it later several times more, with additionally pulling out the accumulator (but unfortunately, as I presume now, only for a couple of seconds).

At the end I've resorted to a navigation via internal SIRF III chip in the PDA.

My hypothesis regarding the malfunction cause.
The accumulator was not fully discharged / charged several times prior to a continuous use of the BT-Q1000X.
A peak current with the new accumulator led to a voltage fall with a consequent system error.
The red Low Battery LED wasn't lighted.

Removing accumulator later and moving the power / mode switch resetted the BT-Q1000X without the need to wait for 5 minutes as suggested in a standard reset procedure.
The BT-Q1000X is functioning properly, probably, till the next malfunction.

Possibly, somebody has experienced the same problems and I'd like to know how they were solved.

What is the toolchain that you used? Do you have the raw bin file? Can you try bin file conversion using BT747?

Well for a start you'll need to have it next to a window if you want it to log the trip, it might keep the fix a bit if you move away but it will eventually lose it. If you have enough memory available you might as well log every second.

BTW is that a direct flight? 14 hours?

No direct, will be a short stop in London, the full flight time approx 16 hours.

Good luck, oh and make sure you don't forget your BT-Q1000X like I forgot mine last year!

The most important thing is to get a fix before getting on the plane and in general that means before getting to the airport.
That allows the device to get the latest Ephemeris and Almanac information (which requires a good reception during 15-32 seconds).

[and remember that there are regulations about using emitters on a plane - the BT-Q1000X has bluetooth]
