It does have a GPS = chip, that chip has the additional functionality that Assisted GPS = offers. Below is the manufacturer information about the GPS chip that is = in an iPad WiFi + 3G. http://www.broadcom.com/products/GPS/GPS-Silicon-Solutions/BCM4750 Don On Nov 27, 2010, at 2:43 PM, Greenbacks, UnLtd. wrote: Hi John, If you have a need to be online at 20k feet, then the iPad with Wi-Fi = and G3 could be one way to go. It has an AGPS chip which allows it to = derive position through communication with cell towers only. The G3 = model has no dedicated GPS receiver and so is incapable of talking to = space vehicles. An iPad with a dedicated external GPS receiver such as = http://bad-elf.com/products/gps/ provides considerably greater accuracy = and unlike communicating with ground cell towers, is less likely to lose = contact with a satellite. So my math looks like this 499.00 for the least expensive Wi-Fi iPad = plus 99.00 for the Bad Elf GPS receiver (I have one), and you're good to = go. The least expensive G3 model is 629.00 plus your monthly connection = charges. How much extra do you pay to connect for 12 months? Either way, just having every approach plate in the entire country on = your iPad for the 75.00 annual cost of a Foreflight subscription makes = it all worthwhile. Angier Ames N4ZQ=
