Precision Analysis and Evaluation of BDS Real-time Precise Point Positioning
In order to test the real-time precise point positioning (PPP) performance of the BDS under different user needs, this paper presents single-frequency nondifference noncombinatorial model, dual-frequency ionosphere-free combined model, triple-frequency ionosphere-free combined model, and evaluates the static positioning performance of PPP. The experimental results show that the positioning accuracy of single-frequency PPP in the horizontal direction is better than 1 cm and positioning accuracy in the elevation direction is better than 10 cm; compared with single-frequency PPP, the positioning performance of dual-frequency PPP is improved by 64.1% in the N direction, 76.8% in the E direction, and 87% in the U direction; and the triple-frequency PPP is more robust in coping with mutations in observation conditions, and the positioning accuracy in N, E, and U directions is 66.3%, 85.7%, and 84.4% higher than that of single-frequency PPP, respectively.
