How to locate Tiantong satellite communication

Tiantong Satellite Communication is a high orbit communication satellite system independently developed by China, which provides users with communication services such as broadcasting, television and data transmission. The positioning of Tiantong satellite communication mainly depends on satellite positioning system and ground measurement and control system.

Satellite positioning system determines the position of the receiver through a group of devices that receive satellite signals. Tiantong Satellite Communication adopts Global Satellite Navigation System (GNSS) to achieve positioning. GNSS is a positioning system using satellite signals, the most famous of which is the American GPS system. Tiantong Satellite Communication Committee receives signals transmitted by several navigation satellites. By calculating the time difference and satellite position information of these signals, the position of the receiver can be accurately calculated.

Ground TT&C system is used to monitor and control the running state of Tiantong satellite communication. By communicating with the satellite, the ground monitoring and control station can obtain the position, velocity, attitude and other information of the satellite in real time, and update the orbit parameters of the satellite through calculation. According to the orbit parameters of the satellite and the received signal information, the position of Tiantong satellite can be determined by ranging and positioning calculation.

Therefore, the positioning of Tiantong satellite communication is calculated by receiving satellite signals and combining with ground measurement and control system. At the same time, it should be noted that the positioning accuracy and availability of Tiantong satellite communication will also be affected by many factors, such as weather, satellite constellation position, receiving equipment performance and so on.
