摘　　要：首先介绍北斗卫星导航系统、全球定位系统及其组合系统伪距单点定位的数学模型和定位处理方法,分别进行了单系统及组合系统伪距单点定位的数据处理实验。实验结果表明,目前的北斗系统伪距单点定位的精度稍逊于全球定位系统,北斗系统及全球定位系统构成组合系统伪距单点定位的精度高于北斗系统的精度,低于全球定位系统。北斗系统伪距单点定位在X、Y、Z方向的精度分别1.60m、4.15m、6.45m,全球定位系统伪距单点定位在X、Y、Z方向的精度分别为1.28m、2.50m和3.6 5m,北斗系统/全球定位系统组合系统伪距单点定位在X、Y、Z方向的精度分别为1.45m、3.15m和4.90m。This paper first introduces the BeiDou navigation satellite system（BDS）, global positioning system（GPS） and BDS/GPS pseudorange point positioning mathematical models and relocation process, and then the experiments of data processing for BDS, GPS and BDS/GPS pseudorange point positioning are addressed. The experiments results show that the accuracy of the current BDS pseudorange point positioning is less than GPS; the accuracy of BDS/GPS pseudorange point positioning is more than BDS and less than GPS. The X direction accuracy of BDS pseudorange point positioning is 1.60 m, the Y direction accuracy is 4.15 m, the Z direction accuracy is 6.45 m, the X direction accuracy of GPS pseudorange point positioning is 1.28m, the Y direction accuracy is 2.50 m, the Z direction accuracy is 3.65 m. the X direction accuracy of BDS/GPS pseudorange point positioning is 1.45 m, the Y direction accuracy is 3.15 m, the Z direction accuracy is 4.90 m.
