Embodiment 1

[0061] In this embodiment, the Tianping-1 satellite ground system is taken as an example. Its work includes two types of daily work and calibration tasks. The calibration tasks can be divided into two types according to the working mode: the central service mode and the independent calibration mode. The center service mode is mainly aimed at users with higher calibration accuracy requirements, and the ground application system provides users with high-precision satellite orbit determination data and related parameters after the event; the independent calibration mode is mainly for users with high calibration accuracy requirements. For high-level users, medium-precision self-positioning data and related parameters will be broadcast in real time when the satellite passes through the border, and the users will complete the data reception and application by themselves. The system workflow is as follows:

[0062] (1) Daily work
