The satellite positioning system is the global positioning system. Simply put, this is a satellite system consisting of 24 satellites covering the world. This system can ensure that four satellites can be observed at any time at any point on the earth, thereby ensuring that the satellites can collect the longitude, latitude and altitude of the observation point, thereby realizing the functions of navigation, positioning and timing. This technology can be used to guide aircraft, ships, vehicles and individuals along selected routes to their destinations safely and accurately.
