摘要

Satellite precise orbit determination based on observation data is a complex work. The method of precise orbit determination based on EKF is studied, and the orbit determination accuracy is analyzed. On this basis, the simulation scene is established based on ODTK software, and the orbit determination accuracy of ODTK and EKF algorithm is compared. The simulation results show that the accuracy of EKF based orbit determination method is close to that of ODTK, and the algorithm can meet the needs of satellite precise orbit determination.
