Abstract

Comprehensive zone correction is a new type of differential corrections for BeiDou wide area augmentation system. As broadcasted together with the equivalent satellite clock and orbit corrections by BDS satellites, they enable user decimeter-level real-time positioning capability using the carrier-phase observations. In this paper, we give a brief introduction of comprehensive zone corrections, and the function model of precise point positioning (PPP) for dual-and single-frequency users using the comprehensive zone corrections. Tracking data of 30 stations in mainland China are used to evaluate the PPP performance, including convergence time, positioning accuracy and its relation with the user's distance from the zone center. Results show that the dual-frequency PPP convergences to 0.5 m in 25 minutes and the positioning accuracy are 0.15 m in horizontal and 0.2 m in vertical, respectively. As for single frequency PPP, the positioning accuracy convergences to 0.8 m in 20 minutes, while the positioning accuracy is 0.3 m in horizontal and 0.5 m in vertical. We conclude that the BDS PPP accuracy using the broadcasted wide area differential corrections reaches decimeter level within the distance of 1 000 km around zone center, and the accuracy becomes slightly worse with the user's distance from the zone center increasing.
