摘　　要：从GPS接收机基站建立入手,通过分析基站坐标的平滑次数、基站坐标偏差、短边点校正及坐标转换模型对坐标定位精度的影响,实测控制点坐标分析误差产生原因及误差的大小,从而指导实际测量工作,减少测量误差的产生。In this paper, starting from GPS receiver base station,by analysis the smooth frequency of base station coordinates, base stations coordinate deviation, short edge Point calibration and Coordinate Transformation Model of impecting of the coordinates positioning accuracy. By measuring the control point coordinates, analysising the size and causes of the error,thus guide the actual measurements, reduce measurement error.
