Accuracy Analysis of Timing Comparison for BDS-3 and GPS Based on Satellite Common View Algorithm

Abstract With the networking completion of Beidou navigation satellite system (BDS-3), BDS-3 was opened in whole world on July 31, 2020. It is important practical significance to analyze performance and GPS terms common view timing comparison. In order accuracy comparison for BDS-3/GPS global time, experimental with medium long baseline carried out based algorithm by using National Metrology benchmark atomic time scale maintained Institute (NIM), China. The model are deduced detail, stability receiver clock difference analysis compared analyzed. results show that respectively ns-level, but slightly better than GPS; 24 ns, GPS.
