Abstract：The reference station selecting during the earthquake is very important for the differential positioning software like TRACK in GAMIT/GLOBK. Some comparisons and analysis about Wenchuan earthquake are done, then we conclude that the for reference station select is most important.In the selection,the observations should be of high quality, the multipath effect should be less than 0.2 m and the distance between rover station and reference station should be more than the product of the velocity of seismic wave propagation multiple by the lasing time. Compared with two undifferenced software GIPSY and PANDA, the results with this method are reliable.
