Abstract:The BDS satellites have yaw attitude maneuver periods and may run in the shadow. These states reduce the orbit determination precision of the dynamic model. In view of the above problem, we use the dynamic orbit determination method, in which pseudo-stochastic pulse parameters are estimated together, to calculate BDS satellite orbits. We analyze the impacts of the pseudo-stochastic pulse parameters estimation schemes on the different estimation intervals of parameters on the orbit determination precisions of BDS satellites’ different statuses, including normal status, yaw attitude maneuver status, and shadow running status. The results show that under the normal status, the precision of GEO satellite orbit determination is improved significantly by the pseudo-stochastic pulse parameters. The estimated interval of the pseudo-stochastic pulse parameters is in good agreement with all kinds of satellite operation periods. For the yaw attitude maneuver status and the shadow running status, the pseudo-stochastic pulse parameters, estimated every 6 hours, are helpful to improve the orbit determination precision of the corresponding satellites.
