摘　　要：为了研究北斗卫星导航系统与全球定位系统伪距单点定位的差异,详细介绍了北斗系统、全球定位系统单伪距单点定位以及双系统联合伪距单点定位的解算模型,并分别编写了北斗系统、全球定位系统单系统和组合后双系统联合伪距单点定位程序。以辽宁连续运行参考站和广西连续运行参考站的数据为实验数据,计算并分析了双系统与单系统相比较的结果。结果表明:在辽宁站上北斗系统定位精度要次于全球定位系统定位精度,在广西站上北斗系统定位精度和全球定位系统定位精度相当。双系统单点定位精度要优于北斗系统单系统定位精度。With the development of the BeiDou navigation satellite system （BDS）, the calculating model of BDS, GPS pseudo-range single point positioning and BDS/GPS double system combined pseudo-range single were introduced in detail in order to study the difference between BDS and global positioning system （GPS） of the pseudo-range single point positioning, and the BDS, GPS system program was written respectively and BDS/GPS combined pseudo-range single point positioning program was wrote. The experiment data of Liaoning CORS station and Guangxi CORS station were adopted, the BDS/GPS double system was calculated, analysed and compared with results of single system BDS and GPS. The results show that BDS positioning accuracy is inferior to GPS positioning accuracy at Liaoning station, BDS positioning accuracy is the same as GPS positioning accuracy at Guangxi station. BDS/GPS double system is superior to single point positioning of BDS system in terms of the positioning accuracy.
