| 摘 要： | 北斗系统现在已经进入了全球组网的阶段。本文详细推导了北斗/GPS组合单点定位的数学模型；设计了两种方案，利用Multi-GNSS Experiment（MGEX）网的实测数据，分别从单个测站和亚太及其周边地区的12个测站来全面地进行北斗、GPS单系统，以及北斗+GPS组合单点定位的精度评价与分析；验证了组合单点定位的数学模型，得出了组合系统单点定位的精度和稳定性均优于单系统的结论，以期为北斗系统的应用推广提供参考。

| Abstract: | BeiDou Navigation Satellite System(BDS) has now entered the stage of global networking.In this paper,the mathematical model of BDS/GPS single point positioning is derived in detail.Two schemes are designed by using the data of one single station or twelve stations in the Asia Pacific Region of the MGEX to evaluate and analyse the accuracy of single point positioning with BeiDou and GPS.The mathematical model of single point positioning is verified by experiments.The results show that the accuracy and stability of the combined single point positioning are better than the single system.This paper aims to provide reference for the popularization and application of BeiDou system. |
