Abstract: Based on the officially released PPP-B2b signal by BeiDou, which carries the precise point positioning(PPP), and the latest high-precision positioning terminal developed by South Surveying & Mapping Technology Co., Ltd.(SOUTH), this article utilizes observation data and real-time positioning results of 6 cities across the country for a week to analyzes the accuracy of the PPP results based on PPP-B2b service. In this paper, the focus is on analyzing the accuracy of real-time static PPP and real-time dynamic PPP positioning. Experimental results show that the static PPP positioning accuracy based on the PPP-B2b service is better than 7 cm in the horizontal direction, and better than 10 cm in the vertical direction; the dynamic PPP positioning accuracy based on the PPP-B2b service is better than 10 cm in the horizontal direction, and better than 15 cm in the vertical direction. A conclusion can be made that the precise point positioning based on PPP-B2b service can reach centimeter level in static mode and decimeter level in dynamic mode.
