Performance of Precise Point Positioning for BDS-3 PPP-B2b Service

A new precise point positioning (PPP) service has been provided by BeiDou global navigation satellite system (BDS-3). The correction parameters are broadcasted by PPP-B2b signal of GEO satellites in real time, including precision orbit correction, clock difference correction and et al. for BDS-3 and other GNSS. The PPP service can be realized with dynamic decimeter level and static centimeter level at China and surrounding areas. Firstly, the area of PPP-B2b service is analyzed based on the threshold of DOP value, and the concerned problems are also pointed out in use, such as the matching problem between correction parameters. Then the evaluation is conducted for three types of correction parameters broadcasted by PPP-B2b. Lastly, the performance of static PPP and kinematic PPP is also evaluated comprehensive, and suggestions is also gave for the PPP-B2b applications.
