摘　　要：GPS控制网成果转换时解算坐标系统转换参数的方法易受到公共点双重坐标精度的影响。文中探讨一种基于稳健估计理论的解算高精度坐标转换参数的方法,算例分析表明该方法实用、有效,在实际工作中应用是可行的。The algorithm of transforming parameters in calculating coordinates could be easily affected by the double coordinate precisions of common points while production of GPS control network is transformed. This paper discusses one way to calculate parameters for coordinates transforming with high accuracy based on the theory of robust estimation. The example indicates that this way is practical and effective, and it＇s feasible in reality.
