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.
