The space segment consists of 24 satellites distributed on the 6 orbit. The height of the satellite track is 20200km, the inclination angle is 55 degrees, and the cycle is 12 hours. The orbital distribution of satellites guarantees at least 6 satellites at any time around the world, and satellite provides users with position and time information to users.
The control section consists of one main control station, 5 monitoring stations, and three injection stations. The main control station is located in Colorado. The monitoring station tracks all GPS satellites in the field of vision, collects satellite ranging information, and sends the collected information to the main station. The main station calculates the satellite precision track and generates the navigation information of each satellite, which is transmitted to the satellite by the injection station.
The user segment consists of a receiver, a processor and antenna. Calculate the user's position speed and time by receiving satellite broadcast information.
The concept of GPS is based on satellite ranging. Users calculate their position by measuring their distance from the satellite. The position of the satellite is known as the location and time signal of each GPS satellite. The time delay of the user receiver measurement signal reaches the receiver, which is equivalent to measuring the distance from the user to the satellite. At the same time, the four satellites can be measured to solve the position, speed and time.
