摘要
以RECO方案[1]为基础,对其抗差估计模型进行改进,并介绍了解算步骤。在此基础上,对GPS一、二级网的七个子网进行了抗差估计,取得较满意的结果,证明提供的模型是有效的。
Based on RECO scheme^([1]), the robust estimation model is improved. A process approach is also presented. Using the improved model, a numerical example for the first-order and second-order GPS net is given. A well result is obtained. It is demonstrated that the new methods can effectively control the influence of outliers to the parameter estimates.
