the GPS system is essentially a broadcast system, the satellites always transmit their time and location and basically anyone can just listen to the signals

GPS was a military system built in the cold war and the signal was purposely scrambled so that only the us military could use it, but since the Soviets already made their own GPS, and at that point they decided that they might as well give access to it for civilian use, as again it’s just broadcasting, the satellites were already there and anyone can listen they just needed to disable the signal scrambling
