Precision analysis of low-earth-orbit satellite orbit determination based on Beidou Navigation Satellite System
With the completion and operation of the Beidou Navigation Satellite System,precision orbit determination of low-orbit satellites based on the Beidou Navigation Satellite System has been widely applied.To effectively evaluate the orbit determination precision of low-orbit satellites based on Beidou Navigation Satellite System,this paper conducts precise orbit determination processing on low-orbit satellite Beidou data using kinematic method,dynamic method and simplified dynamic method respectively.The orbit determination results are verified and analyzed through overlapping orbit difference for internal conformity accuracy and comparison between different orbit determination methods.The experimental results show that error difference RMS between the three precision orbit determination positions is 1.4 cm and the max error difference between the three precision orbit deter-mination positions is 7cm.This result indicates that precision orbit determination based on the Beidou Navigation Satellite System can achieve centimeter level accuracy.
