Abstract:

In this paper the data error property is discussed for GPS crustal deformation monitoring Network of West Antarctic Fildes region,and the systematic error of the data is tested by statistical theory. One method to remove the effect of systematic error from GPS data is given out in this paper also. The method has following 3 features:1.two stable points in the Network are selected as computative datum;2.the scale factor correction and iterative calculation of coordinate conversion are applied to the monitoring data;3.the structure of the Network points does not change after rectified calculation. The systematic error influence is eliminated in rectified data fundamentally.
