Abstract: The BeiDou Navigation Satellite System (BDS) has achieved global coverage. Analyzing the orbit prediction accuracy under different Solar Radiation Pressure conditions is of great significance for improving system positioning accuracy, autonomous navigation performance, and its application development. When satellites are outside the eclipse period, the optimal integration parameters for short-term predictions of the three types of satellites are 900 s and 5th order. For long-term predictions, the optimal integration parameters for GEO and IGSO satellites are also 900 s and 5th order, while for MEO satellites, they are 300 s and 5th order. When satellites are in the eclipse period, it is recommended to use the ECOM9 model for both short-term and long-term predictions of GEO and IGSO satellites. For MEO satellites, the ECOM5 model is recommended for short-term predictions, while for long-term predictions, the ECOM9 model is suggested for MEO satellites with orbit-normal(ON) mode, and the ECOM5 model for other MEO satellites with continuous yaw-steering(CYS) mode. During the eclipse transition period, for GEO and IGSO satellites with ON mode, the effect of solar radiation pressure on orbit prediction accuracy is more significant, while for IGSO satellites with CYS mode, the disturbances caused by the eclipse transition period are effectively weakened. MEO satellites are less affected by solar radiation pressure changes, and their orbit prediction accuracy remains relatively stable.
