Abstract

The whole Beidou Global Navigation Satellite System (BDS-3) constellation was completed and officially announced to provide global service on July 31, 2020. Apart from the global positioning, navigation and timing (PNT) service, BDS-3 also broadcasts real-time precise point positioning (PPP) corrections by 3 Geostationary Orbit satellites (GEOs) via PPP-B2b signal. At present, the PPP-B2b service for GPS/BDS-3 satellites is available for users in China and the surrounding area. In this paper, we conduct the PPP-B2b static and kinematic tests to evaluate the positioning performance of the BDS-3 new PPP-B2b service. Regarding PPP-B2b static positioning performance, the average positioning accuracy are 4.1 cm, 1.8 cm, and 5.2 cm in the east-, north-, and up-components, respectively. Additionally, the average horizontal and 3-dimensional positioning accuracy is about 4.5 cm and 6.9 cm. As to PPP-B2b kinematic positioning performance, the vehicle test results show that the overall positioning accuracy is 25.7 cm and 40.1 cm in horizontal and vertical components. It could be concluded that centimeter-level positioning accuracy is reached in static scenario, and decimeter-level positioning accuracy can be achieved in kinematic scenario.
