Is there a GPS in the iPad Air?
Is there a GPS in the iPad Air that works without cellular reception? A real GPS that determines position from satellites?
首先 你得要准备一部iPad Air（1rd Gen）只支持Wi-Fi的机型 这里我们指的是A1474机型 它拥有64位的A7双核处理器并拥有16,32,64GB甚至是128GB的内存选择
The GPS module is built into the cellular module, so if you buy a Wi-Fi version, there is no GPS capability.
GPS does not entirely rely on a cellular signal; it only speeds up synchronization. Even without any cellular service, GPS will still work fine.
The answer is no.
There is no technical reason why the wireless version should not have a dedicated GPS unit. Apple deliberately restrict this feature in the wireless versions of the iPad.
you have three options.
1. Most expensive:
Buy the 3G/4G version. It has a real GPS built in.
2. Mid Priced:
Buy the wireless iPad and buy a Bluetooth GPS unit. I have the iPad 1, and a dual xgps250. it work fine.
3. Cheapest and best solution.
Don't pretend that Apple makes the best stuff. There are numerous Android tablets that have built in GPS.. Nexus, Asus and Samsung all have great tablets that include GPS.

I am a sailor and use a program called iNav which superimposes my position onto a pre-loaded chart. The purpose of my question was to see if I could pair my iPhone, which as noted in the reponses, does have a GPS ,with a wi-fi only iPad and thus avoid the cost of buying the cell enabled version of the iPad ($130 more).
