Skyhook, it's built in to the iPad OS. If your iPad is on and an application is looking for your location it will query the Location Service Manager which will use the GPS hardware (if present), cell tower triangulation (if you have cell phone hardware) or Wi-Fi (Skyhook) if you have a connection. If all 3 are not available and/or fail then you're just stuck out in the great unknown.
