Abstract

This paper analyzes the precise point positioning (PPP) performance based on the BeiDou PPP-B2b service by selecting static and dynamic scenarios to evaluate the positioning performance of the BeiDou PPP-B2b service in different environments. The results show that: 1) The static positioning accuracy of PPP-B2b service in open environments can reach centimeter-level, with the best results over a 7-day experimental period being 2.18 cm east, 1.26 cm north, and 2.74 cm vertical; 2) The dynamic positioning accuracy of PPP-B2b service in open environments can reach decimeter-level, with the dynamic positioning accuracy in the experiment being 0.14 m east, 0.32 m north, and 1.28 m vertical; 3) The loss of packets during the transmission process of PPP-B2b service can lead to the expiration of corrections, making them unusable. In static positioning scenarios under open environments, the longest time to restore precise point positioning after an interruption is 16 seconds. In complex environments, the interruption of PPP-B2b service is more severe, leading to long periods where the orbit cannot be restored.
