摘　　要：为了分析北斗与GPS伪距单点定位精度的差异,选取南方银河6高精度接收机在湖北理工学院校内4个站点的实测数据,运用伪距单点定位的基本原理和模型进行解算,根据卫星观测数、坐标偏差以及PDOP值变化的差异,比较分析了北斗与GPS伪距单点定位的精度和性能特点。结果表明,北斗的定位精度与GPS的定位精度大致相当,2个系统的定位精度均优于5 m,能够满足普通导航定位的需求。In order to analyze the difference in pseudorange single-point positioning accuracy between BDS and GPS,this paper selects the measured data of the Southern Galaxy 6 high-precision receiver at four stations on the campus of Hubei Polytechnic University.Based on the basic principles and models of pseudorange single-point positioning,the accuracy and performance characteristics of pseudorange single-point positioning accuracy between BDS and GPS are compared and analyzed from the aspects as the number of satellite observations,coordinate deviations,and PDOP values.The results show that the positioning accuracy of BDS is roughly equivalent to that of GPS,and the positioning accuracy of both systems is better than 5 m,which can meet the needs of ordinary navigation positioning.
