Satellite positioning system is a technology that uses satellites to accurately locate something. From the initial low positioning accuracy, unable to locate in real time, and difficult to provide navigation services in time, it has developed into a high-precision GPS global positioning system, which can observe four satellites at any time and any point on the earth at the same time and realize navigation, positioning, timing and other functions.
Satellite positioning can be used to guide planes, ships, vehicles and individuals to reach their destinations safely and accurately along selected routes. Satellite positioning can also be applied to mobile phone tracking and other functions.
