摘　　要：GPS单点定位精度与误差方程的权矩阵相关,合理的定权随机模型能够提高定位精度。目前在用伪距法绝对定位方法解算测站坐标中,定权标准并不统一。通过对基于高度角的GPS单点定位定权随机模型进行研究分析,提出一种新的随机模型,以提高静态单点定位精度。The accuracy of GPS Standalone Position has relevance to the weight matrix of the error equations.So the reasonable stochastic model can improve the positioning accuracy.The standards of determining weight are not unified by using pseudo-range method to calculate station coordinates.By researching the stochastic model of GPS Standalone based on satellite elevation position,a new method is proposed to improve the accuracy of the Static Absolute Position.
