The basics of it are it's a digital synchronized time signal sent out by a constellation of satellites. Devices listen for at least 3 separate streams of time signals and the. triangulation happens to get a position. Irrc the satellite signals not encrypted or whatever were randomized to be inaccurate on purpose. This is mitigated these days by using stuff like cell towers - we know exactly where they are. they pick the same signals out and send out corrections to the randomized data which increases accuracy.
