REGULARIZATION COMBINED WITH ROUST ESTIMATION AND ITS APPLICATION FOR GPS RAPID POSITIONING
GPS快速定位中病态问题的正则化抗差解法

In order to solve the problems of the normal equation being ill-conditioned and observations containing outliers in GPS rapid positioning,a new robust estimate-regularized robust estimate based on the idea of robust M-estimation is proposed.Under this method can solve the robust estimation of ill-posed problems in geodesy.The computation results of GPS data show that the new estimator has the characteristics of resisting outliers,high precision and good stability.
