Good point. I didn't entirely think that through. Bluetooth would be ideal, but I still don't like the idea of a WiFi transmitter attached to me (however, they don't specify power output). FYI - >From what I can tell, it looks like they are using a UBlox[1] GPS chipset and a Sarantel[2] Helical antenna. The GPS chipset is an absolutely outstanding performer, supports multiple GPS constellations, and is *very* expensive (~$100USD for a single chip). The antenna is designed to have maximum gain at altitude, not on the ground. I use them in a couple of projects. I hope this is useful info, Craig.
