TOPIC - APPLE IPAD 1 & 2
9.7" Screen - 1024x768 - GPS Hammerhead II Chipset BCM4751 (3G version)

20110311 - iPad 2 available in the USA, first contact at the Apple Store in Palo Alto and first impressions posted on page 3.


iPad 1 launched in 2010


An iPad will be a challenge on the road without the proper mount !

iPad 3G/32 has come in for testing !

[center]

The Apple web page lists "Assisted GPS (Wi-Fi + 3G model)". Do you guys think GPS applications will be popular with the forthcoming Apple iPad? It is going to be too big for many, but perhaps trucks, buses, and motor home drivers would like GPS functionality on a device this big.

One clarification. GPS is only included in the models which have both WiFi and 3G data. The plus sign is somehwat ambiguous in the web quote.

My guess is that GPS on this device will be all about location awareness tied to lots of functions but not turn-by-turn road navigation, except for pedestrians. Put another way, Apple wants the iPad to now where =it= is so that content can be tailored to that info.

Yes, location awareness is going to be a "must" for app developers, but WiFi might be enough, it's down to 100 meters in urban areas.

As for turn by turn navigation, it does seem "challenging" with the 10" screen, but you do have people currently navigating with latops, so ;-)

Going back to the iPad in itself, it's going to be interesting to see how well it does. The hardware is obviously better than it was in 2000 and the "ecosystem" is there, but the concept is not very different from the "Internet Appliances" launched in 2000/2001 with an alternative OS like BeIA or QNX. Actually Microsoft gave it a shot in 2002 with the [ur="http://www.pencomputing.com/frames/mira.html"]Mira[/url] ! None of them generated enough interest to survive.

The same vague "Assisted GPS" description is used for the iPhone 3G/3Gs, so I would assume there is at least a GPS chipset and not just WiFi for location. 10 inches seems a bit excessive for most turn by turn navigation, but it would be nice to be able to plan a route on the big screen of the iPad and then send it to the iPhone for in-car use.

John Roper

It'll be interesting to see if Navigon, TomTom or others update their turn-by-turn apps. to support the iPad.

And maybe even come out with docks to accommodate it.

Some people will try to mount these things in their cars, just watch.

Dragging routes on a big screen with your fingers? Improvement in usability or gimmick?

It would certainly be an improvement over dragging routes on a little screen. Plus, a lot more real estate.

The ipad is even bigger than the AVMAP EKP-IV http://www.airplanegear.com/avmap-ekp-iv.htm
But it would provide a really nice BIG display for aviation use, if you could get a suitable mount and software. All we need is for a group like these guys http://www.pocketfms.com/ to develop software for the iphone/ipad (they have previously said they wouldn't).

Ohyeah - you would need a proper GPS chip that doesn't rely on cellphone coverage for aviation use too.

I don't know why this bit of misinformation persists. The chip in the iPad is "real" GPS, not something that relies on WiFi or the cell network (and even that function, which I have on my first gen iPhone, is incorrectly called "triangulation" -- it does no such thing).

Perhaps the source of confusion is that only the 3G cell-radio equipped model will come with GPS. But other than that there is no connection.

Yes, shouldn't be any different than the setup on most of the smartphones on the market with a full GPS chip that can get assistance from the network to speed up acquisition but it will work without it.

Now the RF interference of the huge screen should be even worse than what we curently exprience and the GPS antenna will have to be a wire too so accuracy is likely going to be poor, see the iPhone/TomTom Car Kit comparison here : http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=129583&whichpage=2#905658

If the iPad gets jailbroken, maybe the clever RoqyGPS app will work too so you can use any external Bluetooth GPS : http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=132750

Just bumped into this article on cnet : Maps for iPad hands-on. Apparently the "Map" app is a bot refined than on the iPhone as it adds Google's "terrain view". Hopefully that will be added to the iPhone too.

Well I haven't used it yet. I am fully excited regarding my ipad. I had just ordered it and they said that my ipad is in transit. Regarding GPS I think it will be something totally new with such a big screen.

FWIW, TomTom's iPhone app reportedly won't work with the iPad 3G. GPS chipset not recognized. But Mobile Navigator does. Strange.

Someone is going to have to make a mount/cradle.

CoPilot HD screens don't look that imaginative, like side by side 2D and 3D screens.

If the pinch-zooming and scrolling is as smooth as the built-in Maps app., then the turn-by-turn apps. just need to show a big map to fill the bigger screen that is highly interactive.

You could preview your trips better in that scenario, than you could on a standard PND with a 3 or 4 inch screen, where the zooming and scrolling was awkward.

Please post your comments on ALK CoPilot HD in its topic linked above, thanks.

@gatorguy - odd indeed since the GPS setup is apparently identical, must be software related.

In other news, the iPad 3G with GPS pulled apart here : http://www.ifixit.com/Teardown/iPad-3G-Teardown/2374/1


Decent sized GPS antenna de bonne taille, this should help with GPS performance and overcome the RF interference of the screen : http://s1.guide-images.ifixit.com/igi/CV4kNDZfhnsR44Zj.large



Comunication module identical to the one in the iPhone 3Gs with the BCM4750 - Single-Chip AGPS Solution for the GPS part.

Well, apparently someone has already done this. And I suspect that if it fits this well in a Toyota Highlander, it would look awesome in my F150!

Good news, RoqyGPS also works on the iPad those who don't need 3G (the 3G models add GPS as it is located on the same chip), you can save some cash if you alread own a Bluetooth GPS receiver !

As for GPS assisted guidance with the iPad, it can be challenging without the proper mount as I experienced for myself even though I'm used to having a crowded dash ;-)

Enjoying some TBT guidance with CoPilot HD in California on my iPad ;-) It was a snap to get a 3G connection up and running too, walked into an AT&T store, got a microSIM card, then subscribed directly on the iPad for $25/2Gb month to month (had to go back to get a second SIM card though as the first one was defective).

So has anyone used the iPad extensively (more than just trying it out) for TBT?

It seems not all GPS apps. have moved to support the iPad. In fact, most of them have not, if I'm not mistaken. So probably too much to hope they might really take advantage of the larger screen, to let you drag routes in planning and similar features better done on the larger screen.

Some luxury car makers have made iPad mounts in their cars at shows -- may have been concept cars tho.

The tablet category is expected to take off. It may always trail smart phones but should grow so there should be innovation from GPS app. developers.

I used my wife's iPad for a GPS purpose today for the first time, even though I am approx. 90 miles from it at the moment.

We are expecting some very nasty weather and she is on her way back from a meeting in Boston. As of this post her bus is entering Marshfield, MA, southbound on Rt. 3. Obviously I don't know how precise that position is, but I can see the progress of the bus through rush hour traffic as it heads south, displayed on a Google map.

I wonder how often the "Find my iPad" app is going to be named in divorce cases in the coming years [grin]?

Yes, I warned her it has this capability before she fired it up for the first time [g].

It used to come with each MobileMe subscription and is now also free to owners of new iPads and iPhones with no MobileMe subscription or fee required.

I just switched to satellite/hybrid view in Google maps and can tell which lane the bus is in. I'm impressed -- I know the route well enough to verify that it was in the left lane on a road called the Scenic Highway, preparing to turn left and get back on Rt. 6 after a stop at the commuter lot at the Cape Cod Canal. Pretty amazing.

Ah that's the MobileMe app, ok, are you saying it's only free for people who bought their device after a certain date?

As for the accuracy, yes, the GPS engine inside the iPad, the Broadcom Barracuda BCM4750 is second to none!

Eligibility is a little vague. Here's a link to a Macworld article that attempts to explain it:

http://www.macworld.com/article/155878/2010/11/findmyiphone.html

Basically, to get the free service, you have to have at least one device new enough in terms of its hardware, not purchase date, and running iOS 4.2. So older phones that can run 4.2 won't work qualify, but I assume all iPads and all iPhone 4s will. I already had MobileMe, so can't verify this, but I do know that once we activated it all our devices showed up, from my old (retired) Gen 1 iPhone to my wife's iPod Touch, her iPad, and my iPhone 4.

Obviously the non-GPS-equipped devices show only an approximate location based on WiFi or cell, as appropriate, but it's still pretty useful.

Thanks, I'll give it a try on my iPad and 3Gs. I wonder if this can work without a data connection (or data roaming disabled) if the phone is lost abroad, if they use GPRS/3G, it wouldn't.

I have an iPhone 3GS and and iPad. When Apple announced the free version of the Find My iPhone application it said it requires iOS 4.0 or later.

I could not activate the service from my iPhone 3GS, but as soon as the iOS 4.2 upgrade came out for the iPad I was able to set up an account which then also worked to find my iPhone 3GS.

You can even just borrow a friends device (iPhone 4 or iPad with the latest OS), and set up an account for yourself. Then you can disable the service on your friends device but still use it to find your iPhone 3GS.

I'm pretty sure you need a data connection to find the devices.

I just tried the app, and it found both my iPad and my iPhone, even though the iPad was in standby mode (dark screen after sitting idle for a while) and had been in that mode for a couple of hours. I then turned off cellular data on the iPad and the app just sat there trying to locate it.

Another observation:

Both the iPad and iPhone are near the same window in my office,laying side by side. The iPad is located pretty accurately, with a "circle of uncertainty" only slightly larger than the iPad icon. My iPhone is found quite a distance away, with a huge circle of uncertainty. The actual location is within the circle, but the center of the circle is quite far away. I believe the phone is not able to lock to the satellite and is using cell tower triangulation while the iPad does have good satellite lock.

Thanks for the insight, not too surprising for the GPS fix, the 3GS uses the previous Broadcom chipset, the Hammerhead II, a capable chip but much improved on by the Barracuda, also used on the iPhone 4.

Any good car mounts for the iPad yet?

Maybe iPad would be illegal in some states and countries because of the sheer size.

Kind of tough to put up at dash level or above without obscuring the view of the road.

Navigon and some other apps. support the iPad, right, so someone must be thinking about iPads for turn-by-turn use.

This RAM mount works like a charm. $50 at Amazon. In my car, a VW Jetta, I look over the top of the mount (I'm 5' 11") and so it doesn't obscure any of the road. Seeing Navigon on such a big screen is really amazing.

Suction cup stays on the windshield with the iPad attached?

Maybe it could work with something like this too:

Suction cup is one of the best I've ever used. I'm in NJ and a lot of them fall off when the temperature gets really low. This one sticks like a leech.

I have a couple of the Bracketron beanbags and there is no way that it is heavy enough to hold the iPad. It will tip right over.

Now that iOS 4.2.1 has been entirely "freed" I upgraded my iPad and was indeed able to set up a MobileMe "find my phone" account. Actually it's a bit more than that as you can send a message, lock it from a distance and even erase it, I can confirm the first two work well.

I did have to upgrade my 3GS to 4.2.1 too as 4.1 (I think) did not have a way to setup a free MobileMe account.

Does offer some piece of mind. A nice feature would be to be able to give a "view only" link to friends and family, although I guess that for that there is Google's Latitude or the free "GPS Tracker" app.

iPad 2 launched today by the "man" himself : http://www.apple.com/ipad/ and available very soon, on March 11th. Time to pay the local Apple Store a visit! It's going to be hard for iPad 1 owners to resist the temptation to upgrade ;-)

In terms of navigation experience, there is apparently a new gyro, not sure if that will have an impact. It will be interesting to see whether the GPS chip is still by Broadcom/Globallocate, we'll have to wait for an iFixit "teardown" for that. The current one, the BCM4750 "Barracuda" certainly performs very well.

There's been some speculation that an iPad 3, with possibly a Retina Display, would surface later this year, rather than a year from now.

People will speculate on anything...apparently that rumour has been taken care of it seems and I couldn't see Apple breaking their usual schedule unless their market share tanked, and an iPad 2 with a Retina Display wouldn't do miracles in that respect would it.

Anyway, back to the iPad 2, the replay of the launch is now available : http://www.apple.com/apple-events/

This has probably been answered/discussed a gazillion times, but is the GPS chip in both the WiFi and WiFi-3G versions of the iPad, or just the Wifi-3G version?

Just on the 3G version on the iPad 1, most likely the same for the iPad 2. You can connect to an external Bluetooth GPS with a jailbroken iPad/iPhone though -> http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=132750

Looks like the iPad 2 has a Broadcom BCM4751IUBG chip on the 3G GSM version. Is that different from the original iPad?

Has it been "teared down" on iFixit? Last I looked they'd worked on the WiFi version only, let's see...nope, where did you see that?

In any case, yes the Broadcom/Globallocate BCM4751 chip, codenamed "Barracuda", is the GPS chip used on the iPad 1 and the iPhone 4.

I checked out the iPad 2 last Friday at an Apple store :


Quick comments :
- As announced it's light and fast!
- Skype for iPhone works with the front camera
- The finish of the white model was a bit disappointing with the "yellowish" border between the bezel and the screen. Probably due to the glue/bonding, but it makes it look a bit dirty (see pictures below, although hard to capture).
- The "smartcover" is very sleek (touch, thin, interaction with screen) but as I feared it doesn't hold that well and you'll have to be careful not to lose it. The "writing" position (top part higher) is awkward as the iPad doesn't rest entirely on the folded cover, so if you press a bit hard it comes off.


NOW FOR SOME PICTURES

Not sure about the "IUBG" part, maybe the format, but it's most likely the same.

Not cheap to manufacture are they at about $325 for the 32Gb WiFi version, the markup on the 3G version is huge though since it apparently only costs $10 more to build!

If you don't want to spend the extra $130 for a 3G/GPS version and you still need GPS from time to time you can use the TomTom Car Kit and a cheap iPhone extension cable:



Probably not useful on a daily basis but could come in handy. It won't power up the iPad though.
