Abstract
Precise point positioning (PPP) technology is a positioning enhancement technique that can cover a large area and reduce the cost of positioning. With the support of real-time precise orbit and clock offset products, the global real-time PPP can be realized, which greatly improves the effectiveness and availability of the results. First, in this paper, the global real-time precise orbit and clock offset can be calculated by the BeiDou global continuous tracking station. Then the BeiDou global-enhanced message is designed, the frequency and the type of broadcasting-enhanced message are analyzed. Finally, the real-time PPP accuracy of BDS is studied. The actually measured numerical example shows that the real-time PPP based on BDS can achieve decimeter-level position accuracy in the Asian-Pacific region.
