Abstract

Objectives Although the precise point positioning (PPP) can provide global cm-level positioning, it takes tens of minutes to converge. While PPP-RTK (real-time kinematic) relies on regional reference stations to provide atmospheric delay corrections to accelerate the convergency, however, only the regional service can be provided.
Methods PPP with multi-frequency and multi-GNSS observations is presented, and only the satellite orbit, clock and observable-specific signal bias (OSB) are needed to achieve instantaneous cm-level positioning. This approach solves the problems of slow convergence of PPP as well as the limited-service scope of PPP-RTK. Furthermore, a wide-area instantaneous cm-level service system compatible with BDS(BeiDou satellite navigation system) PPP-B2b service is proposed, and the performance of real-time orbit, clock and OSB is evaluated.
Results The results of static and in-vehicle kinematic data in China confirm that the system can provide cm-level precision positioning within 1 min.
Conclusions It's implied that our system bears the ability to meet the needs of fast, high-precision and high-confidence positioning in autonomous driving and other fields around the world.
