Title
BDS precise point positioning ambiguity resolution with high rate data and its application to seismic displacement and marine surveying
Abstract
Precise point positioning (PPP) with ambiguity resolution (AR) has been proved to be an effective method to improve the positioning accuracy and shorten the convergence time, which plays an important role in geodetic and geodynamic applications. In this study, the performance achieved based on the BeiDou Navigation Satellite System (BDS-2 and BDS-3) joint PPP-AR with high rate data was considered and the validation of its application to seismic displacement and marine high-precision surveying was evaluated. First, the methods of uncalibrated phase delays (UPDs) estimation and PPP-AR were introduced. Next, the performance achieved based on BDS PPP-AR in both static and simulated real-time kinematic mode was evaluated with hourly data selected from 16 tracking stations over 3 days and data sampling rate of 1 s. After convergence, the positioning accuracies in the east, north, and up directions were 3.4 cm, 1.5 cm, and 5.5 cm, which were improved by 11.9%, 3.8% and 2.2% compared with the float solutions. Finally, a test of applying BDS PPP-AR to marine surveying was carried out with two hours data collected from two independent GNSS receivers installed on a boat sailing along the coast of Bohai Sea, China. The onboard two data set are processed in post-processing kinematic BDS PPP mode. The accuracies were improved from 2.4 cm, 3.5 cm and 4.0 cm to 2.2 cm, 3.1 cm and 3.1 cm in the east, north and up directions by ambiguity resolution, with improvements of 8.3%, 11.4% and 22.5% over the float solutions. The results validated the feasibility of the BDS PPP-AR for high-accuracy maritime applications.
