Precise Single Point Positioning Method and Result Analysis Based on BDS-2/BDS-3
Currently,the full operation of the Beidou-3 Global Satellite Navigation System has been successfully achieved with com-prehensively developed key technologies,such as BDS-3 navigation chips and modules. As a high-accuracy positioning technology,Precise Point Positioning (PPP) has been widely applied. Accordingly,research related to Beidou-3-based PPP positioning has be-come a hot topic. In this study,using measurement data collected from the MGEX tracking station,we performed comparative analysis of static and dynamic PPP positioning accuracy among four different modes of PPP positioning solutions:BDS-2,BDS-3,BDS-2/BDS-3,and GPS. The results indicated that the addition of BDS-3 satellite significantly improved PPP positioning accuracy with static and dynamic PPP positioning in three directions.
