| Abstract: | 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. |
