>GPS devices don’t actually contact satellites and transmit information to them. They only receive data from satellites – data that’s being always-transmitted.

>A device with built-in GPS – whether it’s a dedicated in-car GPS navigation unit or a smartphone – only acts as a GPS receiver. A device with GPS isn’t actually “contacting” satellites to determine its location. Instead, it’s just listening for the radio signals that are being broadcast from these satellites all the time.

>A GPS receiver “listens” for signals from four or more satellites. Signals from the closer satellites will arrive sooner, while signals from the farther satellites will arrive later. (The actual time difference is very small, but can be detected by the GPS receiver.) By comparing the time the signal was broadcast and the time the signal arrived, the receiver can estimate its relative distance from all four satellites. Using trilateration, the receiver can then determine its location.

>It's called incoming trilateral communication and a car CAN transmit the incoming data

its called TRIANGULATION you fucking blithering idiot and you can do it with a map and a compass no electronics required. GPS units do not transmit. at all. ever. it's a glorified FM radio.
