摘　　要：本文对目前国际上所有的GPS伪距单点定位算法,即线性最小二乘法、非线性最小二乘法、格网搜索法、kleus法的基本原理及程序实现步骤进行了阐述,并从算法的可靠性、准确性及作业效率等方面进行了综合比较分析。All single-positioning algorithms implemented in the GPS data processing, including linear least square method, nonlinear least square method, grid searching method and kleus method, were presented in this paper. Their basic principles and programming procedures were discussed separately and their corresponding quantities of reliability, accuracy, efficiency were analyzed simultaneously.
