摘　　要：首先简要介绍了GPS伪距单点定位的基本原理,在此基础上推导了GPS(组合)伪距单点定位的数学模型。然后,利用笔者编制的GPS(组合)伪距单点定位软件,结合实际算例对GPS(组合)伪距单点定位的精度进行了较深入地研究和探讨,得出了一些有价值的结论。Firstly,basic theory of GPS pseudorange point positioning is briefly introduced in this paper. On the basis of it, the mathematic model of single point positioning using GPS combined pseudorange is demonstrated. Then, the software of single point positioning using GPS combined pseudorange compiled by the author is applied, and single point positioning accuracy using GPS combined pseudorange is profoundly researched by means of the practical examples . Finally, some useful and important conclusions are given.
