1. Ground control section
The ground control part is an important part of satellite navigation system, which consists of ground measuring station, monitoring station and control center. The ground station is used to measure the satellite's orbit, clock error, ionosphere and other data, the monitoring station is used to monitor the state and health of the satellite, and the control center is responsible for the overall operation and maintenance of the satellite navigation system.
2. Space part
The space part is the core part of the satellite navigation system, which consists of several satellites. These satellites are distributed in different orbits and constantly send signals to users, providing services such as positioning, navigation and timing. The success of satellite navigation system depends largely on the number, distribution and performance of satellites.
3. User part
The user part is the ultimate beneficiary of satellite navigation system, which consists of receiver and user terminal equipment. The receiver receives the signal transmitted by the satellite, and obtains its position, speed, time and other information through signal processing and calculation. User terminal equipment is used to show these information to users to meet their actual needs.
In a word, the three components of satellite navigation system are inseparable, and only by cooperating with each other can we provide users with high-precision and reliable navigation services. With the continuous development and perfection of satellite navigation system, its application scope is more and more extensive and it has become an indispensable part of modern society.
