BDS-3 provides three kinds of Radio Navigation Satellite Services (RNSS), including primary Positioning Navigation and Timing (PNT), Satellite Based Augmentation System (SBAS) and Precise Point Positioning (PPP). Satellite phase center offsets are important error sources for service performance. Misalignments of frequency-dependent phase centers decrease the service performance further. Therefore, approaches accounting for satellite phase center offsets and the misalignments are prerequisite for satisfactory service performance. Phase center offsets induced errors on ranging and positioning accuracy are analyzed. Different feasible approaches accounting for phase center offsets are presented with reached accuracy. Finally, optimal approaches accounting for the phase center offsets are concluded for all the kinds of RNSS services with real measurements.
