F5 to run and create the animation file named 'GPS_constellation &_working_principle_model.gif' that will appear in the same directory as you registered this .m file.

Dashed green lines links show visible spacecrafts (white dots) at a certain time on a certain place on the planet.

Theoritically minimum satellites vsible in the sky to give position and time is 4 (three for position, one for time)

Orbital angle values are slightly different from reality.

Old piece of code (updated for gif creation but not optimally factorized), but this is not the main thing here.

Please rate if it helped you. Thanks.
