To 99% of tablet users, "GPS" = "Google Maps" or some similar mapping tool that is constantly reaching into the cloud to pull in the next bit of map data, search for restaurats around your current location, compute driving directions on demand, pull up real time traffic data, etc., etc.
But if what you mean by "GPS" is "Can the device compute my lat/lon/altitude and make that information available to apps independent of internet access", then any Android phone or tablet will be able to do that. (Not all iPads can...only the ones with celluar data capability also include built-in independent GPS receivers.)
Note that if you plan to use your Android device in conjunction with an external ADSB-in receiver (like a Stratux), then that ADSB device will have its own GPS receiver and iFly will give preference to that external GPS, only falling back to the Android internal GPS if the external receiver is unavailable.
