Paper Abstract

The Beidou-2 navigation system is a self-developed and independently owned global satellite navigation system. It can realize three functions of positioning, communication and timing. How to improve the positioning accuracy has always been an important issue that all parties are determined to solve. In this paper, the principle and mathematical model of single-point positioning and pseudo-range differential positioning are introduced in detail. The positioning accuracy of the two methods is compared by the emulated data. The results show that differential positioning can improve the positioning accuracy. In addition, as the distance between the base station and the rover station increases, the positioning accuracy decreases gradually.
