- dingaling 12y agoWhat do you mean by "GPS transponders"? A transponder replies to an interrogation with a squitter response. Navstar satellites zip along merrily broadcasting to anyone who will listen ( regardless of the receiver's ability to process the signal ). You as an intending user don't communicate with them at all. In the receiver there is no transmission capability related to GPS. Why would there be? The only uplink to which Navstar sats will listen is that from Boeing's system control center ( or presumably a spoof thereof ).
