The iPad Air is in the middle of Apple’s tablet lineup when it comes to features and price.
AIR NAVIGATION PRO IPAD PRO
Air Nav Pro I'm only just getting used to but it seems to be just as good for accuracy.IPad Air Fourth Generation Jacob Krol/CNN I've used my Iphone 3G as a GPS backup for a while now and with Memory Map it is very accurate whilst flying (verified by good old fashioned mk1 eyeball and ground features). I don't know why an ipad 3G would be worse in flight than an iphone for GPS because I would assume that Apple use the same kit for both. Non-3G ipads have no GPS at all but can get a basic position from the internet via wifi. If no 3g/wifi is available then you can still get a GPS fix in the same way that a garmin or tomtom does, but it takes the same amount of time as a non-assisted GPS.
AIR NAVIGATION PRO IPAD FULL
A-GPS is a full GPS system which is assisted in it's initial position fix by the 3G or wifi network available, which means you normally get a fix within 5sec or so. This has gone around a few times with people saying that this is a cut-down version of GPS but this is not the case. Ipad 3G, Iphones, and most other 'smart' phones use assisted GPS (A-GPS). WiFi only models have something which, it seems to me wrongly, they refer to as A-GPS.

So the WiFi version uses Skyhook, which could not work in the air (ironically). The 3G model contains A-GPS to allow its position to be calculated with GPS or relative to nearby cellphone towers it also has a black plastic accent on the back side to improve 3G radio sensitivity. Wiki wrote:The iPad can use Wi-Fi network trilateration from Skyhook Wireless to provide location information to applications such as Google Maps. Please don't take this as gospel I am as confused as anyone else, but that is the way it seems to me, and may explain apparently odd iPad GPS behaviour. Apps behave as if it had GPS on the ground, providing WiFi is in range, as far as I understand it. It seems that the WiFi version of the iPad uses the augmentation exclusively and has no true GPS at all. WiFi only models have something which, it seems to me wrongly, they refer to as A-GPS.Ī-GPS, at least according to Wiki, is supposed to be GPS augmented by use of WiFi to augment position finding. I think that the variable reports may be based on what seems to be a little known fact that only 3G iPads have true GPS. The iPad I have heard very variable reports on yesterday I flew with a friend with an iPad and it lost GPS reception repeatedly, every time he closed the lid on the iPad "folder".

The Iphone has an excellent GPS, on the ground. There is also a version of this file running under Oziexplorer, which itself does not yet exist for the Iphone but the developer says it soon will. The CAA maps now come in QC3.įortunately the whole of the UK now exists as a single QCT map, downloadable on the P2P scene - probably generated from somebody having scanned the three maps and stitched them together, georeferenced them, and generated a fresh QCT. Those files are locked to the hardware, via some sort of licensing scheme. No idea about the new QC3 "digital rights managed" encrypted format.

Their bottom product (£10 from the Apple shop) can't load QCT maps I think it works only with maps you buy and download (MM never responded to my emailed questions, ever). I have done this on my GF's Iphone 4, and it does work quite well. about £20) Iphone MM version can load any QCT map file.
