摘要
为确保 GPS监测网变形分析结果的正确性 ,提出了 3种平差方法 ,并采用基于标准化残差的抗差估计模型来识别观测值中的粗差 ;利用坐标系统转换方法统一了变形分析的基准 ,通过对具有粗差的模拟 GPS监测网的分析计算 ,取得了满意的结果 .
In order to obtain right analytical results of GPS monitoring network, three kinds of adjustment methods were put forward, and the robust estimation model for correlated observation based on standardized residuals was used to identify the gross errors in observation values. The data deformation analysis was unified by coordinate system transform. Satisfictory results have been obtained by calculating and analyzing a simulating GPS monitoring network with gross errors in observation.
