Analysis and Application of Precision Point Positioning Service of Beidou-3

In order to improve the competitiveness of the Beidou-3 system in the field of high-precision applications, a precision point positioning service is planned and designed for the Beidou-3 system. Based on the interface control document of precision point positioning (PPP) service, the signal of Beidou-3 PPP service is analyzed, and a user application algorithm is proposed in this paper.At last, the experimental verification results of the Beidou-3 PPP service are given. The test results show that the horizontal positioning accuracy of the Beidou-3 PPP service is better than 0.3m, the elevation accuracy is better than 0.6m, and the convergence time is less than 30 minutes.
