[Abstract]:With the rapid development of space information technology in the new century, the role of satellite navigation and space position service in military, traffic and daily life is becoming more and more important. The satellite navigation systems that have been built and can operate autonomously include GPS of the United States and GLONAS Ss of Russia. In China, the independent Beidou Satellite Navigation system (BDS) has been put into trial operation. By the end of December, 2012, there will be 14 satellites in orbit. In order to realize the high precision application of Beidou system, it is necessary to obtain satellite precise orbit and satellite precision clock difference products. Aiming at the determination of precise orbit and precise clock error of Beidou satellite, the correction methods of perturbation error in orbit determination are studied in order to improve the accuracy of orbit determination, and the ability of high precision positioning in Beidou is analyzed. The experimental results have certain reference value for the service ability of Beidou satellite navigation system. The main research contents are as follows: 1. This paper summarizes the construction of satellite navigation systems in various countries, and analyzes the current research status of satellite navigation system data quality analysis, precision orbit determination and precision single point positioning. This paper generalizes the method of navigation satellite data processing. 2, discusses the theory and foundation of navigation satellite data processing, expounds the theory and method of Beidou satellite data preprocessing, and analyzes the applicability of various methods by experiment. The data quality control of Beidou satellite navigation system is comprehensively controlled. The theory of precise orbit determination of Beidou satellite is studied, and the influence of various perturbation forces in the course of orbit determination is analyzed. Then, based on the regional monitoring station and the global monitoring station, the precise orbit determination of Beidou satellite is carried out, and the effects of "one-step method" and "two-step method" on orbit and clock error are analyzed. In this paper, the orbit determination accuracy of Beidou satellite is given. The static precision single point positioning and quasi dynamic precision single point positioning are calculated by using high precision satellite orbit and clock difference products, and the calculated precision orbit is analyzed. Bell differential products Beidou system can reach the level of service.
