Abstract:

In this paper, a kinematic precise point positioning（PPP) model of BeiDou System(BDS)/GPS using zone corrections is proposed. Fifteen MGEX（multi-GNSS experiment） stations are selected as reference stations or evaluation stations. Then,the accuracy and the convergence of kinematic precise point positioning of BDS/GPS are analyzed based on 20-day data. Results show that BDS dual-frequency kinematic precise point positioning converges to 1 m in 13 min on average and the coordinate accuracy reaches 0.15 m in horizontal and 0.30 m in vertical component after convergence. The BDS/GPS dual-frequency kinematic precise point positioning shows better accuracy and shorter converge time, which converges to 1 m in 3 min on average and the coordinate accuracy is less than 0.07 m and 0.15 m in horizontal and vertical component, respectively.

Key words:BeiDou System(BDS) and GPS combined(BDS/GPS);zone correction;precise point positioning(PPP);convergence time;positioning accuracy
