    Wow this is so cool!! I did know it was timing based and needed to be precise, but this is so crazy! And to think we’ve gotten so good at making these precise timing circuits to just add them to all phones like it’s nothing! This is really cool! And the part about spoofing GPS in planes, that is even crazier how can anyone accomplish that is beyond me it’s pretty much magic at this point that’s so cool!!

      In the cell phone there are specialized chips that “just” read the signal. They use some interesting tricks to catch the timing right, but can’t be used to produce such a signal. The satellite “just” sends a signal with it’s own position and the timecode (based on it’s own atomic clock). And those nanoseconds and picoseconds of difference when the signals from different satellites arrive determine the distance to those satellites, and together with their position, one can calculate the receivers location.
