Precise orbit determination for BDS satellites

Abstract Since the first pair of BeiDou satellites was deployed in 2000, China has made continuous efforts to establish its own independent Navigation Satellite System (BDS) provide regional radio determination satellite service as well and global navigation services, which rely on high quality orbit clock products. This article summarizes achievements precise (POD) BDS past decade with focus observation dynamic models. First, disclosed metadata is presented contribution POD addressed. The complete optical properties bus solar panels are derived based absorbed parameters material properties. Secondly, status tracking capabilities L-band data from accessible ground networks presented, while some low earth orbiter onboard capability listed. topological structure measurement scheme Inter-Satellite-Link (ISL) described. After highlighting progress models perturbations for BDS, e.g., phase center corrections, attitude, radiation pressure, different strategies used summarized. In addition, urgent requirement error modeling ISL emphasized analysis noises, incompatible characteristics illuminated discussed. further researches improvement calibration models, refinement potential estimation geodetic or identified. With this, it promising that can achieve better performance provides vital contributions geodesy navigation.
