Performance analysis of real-time precise point positioning with GPS and BDS state space representation

The third-generation BeiDou Navigation Satellite System (BDS-3) has global networking in July 2020, multi-constellation Precise Point Positioning (PPP) with GPS, BDS-2 and BDS-3 has become a more accurate global positioning technique. With the improvement of state-space representation (SSR) in 22 Ma...
