It is composed of three parts: space satellite, ground monitoring and user receiving. There are 24 satellites in space to form a distributed network, which are distributed on the earth's accurate simultaneous tracks with 20,000 kilometers from the ground and a tilt angle of 55 °. There are 4 satellites on each orbit. GPS satellites around the earth every 12 hours, enabling the places for the earth to receive 7-9 satellites at the same time. There are 1 main control stations and 5 monitoring stations on the ground responsible for monitoring, remote testing, tracking and control of satellites. They are responsible for observing each satellite and providing observation data to the main control station. After receiving data from the main control station, calculate the accurate location of each satellite at each moment, and transmit it to the satellite through 3 injection stations. Essence
Note: This system was initially developed by the three Army of the United States, sea, and air in the 1970s. Its main purpose is to provide real -time, all -weather and global navigation services for the three major areas of land, sea, and air. Some military purposes such as explosive monitoring and emergency communication are important deployments of the United States ’global strategy. After more than 20 years of research experiments, the GPS system spent 30 billion US dollars. It was not until March 1994 that the global coverage rate of up to 98%of the 24 GPS satellite constellations were officially set up. The application of the GPS system is not limited to the military field, but has developed into various fields such as car navigation, atmospheric observation, geographical survey, marine rescue, manned spacecraft protection and detection
