doi:10.13474/j.cnki.11-2246.2017.0389

Abstract

Abstract: In view of the influence of the gross error of the ERS point on the accuracy of the measurement field, this paper presents a robust method for judging the gross error of ERS point. In this method, the suspicious points are obtained by the initial screening of the Lai criteria, and then the faulty points are discriminated by the Romanovsky criterion, the anomaly points are determined and removed, and finally the SVD algorithm is used to calculate the station parameters. The results show that the method can accurately eliminate and improve the overall accuracy of the measurement field.

Key words: ERS point, gross error discrimination, measurement field, station parameters, SVD algorithm
