    Actually it is not true GPS but A-GPS. It's a sort of assisted GPS. It works by triangulating your position from cell towers in the same fashion a GPS uses satellites. It only works with 3G models in conjunction with GPS apps. If you fall out of cell reach, I'm pretty sure it won't work.

    the iPad has a True GPS. It is accurate within 15 feet.
    The iPad 3G is the model with GPS, wifi only ipad does not have GPS. Also like the poster above said it uses whats called an Assisted GPS. This means that it can find your location mutch faster than a normal GPS.

    First it uses the cellphone tower to get the city location for where your at. This means it knows right off the bat the general location/city your in and the actural GPS doesnt have to work as hard to pinpoint your exact location.

    If the 3G service on the ipad is disable the GPS will still function since it is a true GPS.


    As far as GPS software, it only comes with a google maps app. other GPS software is downloaded from the app store.

    You can download apps that do.

    Best one would be Navigon.

    Thanks for the clarifications, MikesTooLz.

    The Wiki I got that from will have to be updated...:D

    There seems to be a lot of confusion with the GPS. I had friends tell me after I bought my iPad that A-GPS is inferior and not "true" GPS but relies on cell towers (like the above poster which was mistaken).

    Like the other poster above, A-GPS is "enhanced" and therefore sometimes faster than regular GPS as it uses both cellular and satellite. Satellite location will always be used as the primary as cellular triangulation is not quite accurate, however it speeds up the initial tracking to your region faster than the satellite will - in other words it "assists" the actual onboard GPS chip. Personally I have yet to activate my 3G and my GPS still tracks me within 30 seconds or less (unless way indoors).

    I have had a GPS location on my iPad when I have had cell no service with AT&T on my iPhone, so it certainly must be using satellites.

    And, here's a tougher question: since my iPad is wifi only, how could it be using cell towers anyway, unless it has the 3G hardware installed, but doesn't enable it for use?

    WiFi-only units use the location of the wireless network you are connected to.

    Oh, that's a good one. For a moment, though, I thought you were serious. LOL.

    Wow, you are kind of serious. Where I usually am, the only wifi's my iPad sees are private, like the one at my house. You don't get a myriad of wifi's when you live in the middle of nowhere.

    Hmm. So my wifi-only iPad does not have gps. Wow, I didn't realize that. It sure does a dang good job finding itself then.

    WiFi only iPads certainly can determine your location

    can determine your location but accuracy goes out the window.

    you could be next to a wifi hotspot that someone registered in another country and the wifi only ipad would then think your in the other country.

    iPad 3G are the only ones with GPS.

    I was trying to cover up the horrifying truth. When you buy an iPad, one of the sales associates sneaks up behind you as the box is being opened and injects a GPS microchip in your hip. :eek:

    Interesting...

    Have you tried this in a vehicle to see how accurate it is? I'd be curious.

    Home position is easy, the iPad has our address. But moving away from it?

    If moving away, unless the wifi is off, the radio tries joining a network and gives its information. Can it be detected by public networks as it does so? Btw when the iPad is in sleep mode, wifi keeps emitting.

    Is it possible for an IP or MAC address to give its position on a "web map"?

    Well, I did the perfect test today. My wife and I went for a two hour cruise on the Saint Lawrence river this afternoon. The part we were at had a width of about four miles. In port I turned the iPad on with 3G working and opened iPad Maps in satellite view. About 20 minutes in, 3G faded to signal loss but our position kept updating precisely until the maps were gone. As we neared the coast 3G came back and the maps updated without real change to our actual positioning. After a while i turned 3G off. No difference, our position kept updating to around 20 feet.

    There surely is a GPS onboard the iPad. Test confirmed. Having 3G only aids to keep the maps displaying in sync with position.

    Get MotionX GPS HD and you can download the maps and store them on the ipad. When 3G dies you still have your maps :)
