Unless there's a dedicated GPS receiver chip in there (which I don't see), the answer is currently no until apple makes the Bluetooth serial profile available (so standalone units could be used) or someone finally ships a receiver that connects to the accessory port. Same for a compass/magnetometer.
can you give more info on this?
what do you mean by "or someone finally ships a receiver that connects to the accessory port" ?
