Abstract

Following American Satellite Navigation Global Positioning System (GPS), European Galilean System and Russian GLONASS System, BeiDou Navigation Satellite System (BDS) has become the fourth navigation satellite system in the world, and research on the BeiDou Positioning System become more and more in-depth. Gauss-Newton Iterative Least Squares (GNILS), which is now generally used in pseudo range single point positioning, has a strong dependence on the initial value and massive iterative calculation. In this paper, a PVT algorithm based on weighted least square is applied to calculate the positioning accuracy of the second generation of BDS (BD2). Measured and simulated results show that compared with direct calculation and least square, the proposed algorithm greatly improves the positioning accuracy, and has a good computational stability, thus to meet the application of civil navigation.
