At the beginning of the 321st century, gps became civilized and was widely used in the fields of transport, mapping, meteorology and environmental protection. The gps foundation satellite launch signal gps satellite sends a radio signal to the ground, containing the satellite's status and time information. The receiver receives the signal from the satellite and records the time of receipt of the signal. The gps receiver, which calculates the coordinates of the position, calculates the coordinates of the position, speed and time by the time difference of the three satellite signals. The gps system consists of approximately 30 satellites that send a global signal and provide global coverage of positioning services. Earth control stations maintain satellite operations, modify and update satellite information. User receivers receive satellite signals, calculate and display information on the location, speed, time, etc. Of users.
