【摘要】：进入新世纪以来,空间信息技术得到了飞速发展,卫星导航与空间位置服务在军事、交通及日常生活中的作用越来越重要。目前已建成并能自主工作的卫星导航系统包括美国的GPS及俄罗斯的GLONAS S。我国建设自主的北斗卫星导航系统(BDS)已开始试运行,到2012年12月底在轨正常运行卫星达14颗。为实现北斗系统的高精度应用,需要获取卫星精密轨道及卫星精密钟差产品。针对北斗卫星精密轨道及精密钟差确定问题,通过研究定轨中的各种摄动误差改正方法,以提高定轨精度,并进一步对北斗高精度定位的能力进行分析。实验结果对现阶段北斗卫星导航系统的服务能力有一定的参考价值。主要研究工作内容如下：1、概述了各国卫星导航系统的建设情况,分析了目前卫星导航系统数据质量分析、精密轨道确定及精密单点定位的研究现状,从总体上概括了导航卫星数据处理方法。2、探讨了导航卫星数据处理中的理论与基础,并阐述了北斗卫星数据预处理理论及方法,采用实验分析各种方法的适用性,对北斗卫星导航系统的数据质量控制有了全面的把握。3、研究了北斗卫星精密定轨的理论,并对定轨过程中的各种摄动力影响进行分析。然后分别基于区域监测站和全球监测站对北斗卫星进行精密定轨,分析采用“一步法”定轨和“两步法”定轨对轨道和钟差的影响,给出目前北斗卫星所能达到的定轨精度。4、利用高精度的卫星轨道及钟差产品,分别进行静态精密单点定位及准动态精密单点定位计算,并分析采用计算出的精密轨道、钟差产品北斗系统能达到的服务水平。
[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.
