几何定轨方法不受力学模型误差的影响，过程简单，但是定轨精度不高，轨道外推精度也得不到保证。动力法定轨精度较高，但是在完成观测数据积累之前无法定轨，并且受到力学模型精度的影响。本文结合几何法和动力法的优点，研究了基于几何法的动力学定轨方法，仿真结果表明：该方法可以得到优于几何法的定轨结果，并且结果比较稳定。

Geometric orbit determination method is not a mechanical model error , the process is simple ,but the orbit determination accuracy is not high ,the track extrapolation accuracy can not be guaranteed .Dynamic orbit determination accuracy is high ,but unable to orbit determination ,and before the completion of the observational data accumulated by the mechanical accuracy of the model .In this paper ,the advantages of the geometric method and dynamic method to study the orbit determination based on the geometric method of dynamics simulation results show that this method can be better than the geometric method of orbit de‐termination results ,and the results are relatively stable .
