Abstract

Abstract: The phase center corrections (PCCs) for TRM57971.00/NONE and TRM59800.00/NONE antennas on GPS L1 and L2 as well as BDS B1I and B2I frequencies were calibrated by automatic robot. Additionally, the differences between calibrated PCCs of GPS L1 and L2 as well as BDS B1I and B2I were compared. Three kinds of BDS precise orbit products were determined with or without accounting for the receiver antenna's Phase Center Offsets (PCOs) or PCCs based on about 31 stations from International GNSS Service (IGS) Multi-GNSS Experiment (MGEX) network to investigate the impacts of receiver antenna on BDS orbits. The results demonstrated that the overlapping orbit differences of BDS Inclined Geosynchronous Orbit (IGSO) satellites were improved by 63.1 mm, 21.5 mm, and 6.7 mm in along-track, cross-track, and radial directions, respectively. For BDS Medium Earth Orbit (MEO) satellites, the improvements can reach to 217.1 mm, 75.8 mm, and 23.3 mm in along-track, cross-track, and radial directions, respectively, when the PCOs only have been used for precise orbit determination. And the similar performance has been achieved by using PCCs as that of using PCOs only. The accuracy of precise point positioning improved nearly 10.0 mm in up direction once the calibrated PCCs were used.
