In order to discuss the possibility to applying the Precise Point Positioning based on epochdifference model in ground surface deformation monitoring,the paper analyzed the accuracy of the proposed method by using the data of IGS tracking stations:with the help of self-developed program,the processing with different sampling data in dynamic simulation and error statistics were carried out;the precision of based on epoch-difference model was analyzed preliminarily,and the influences of GPS data sampling on the precision of were verified finally.Experimental result showed that the method could meet the precision requirement on co-seismic ground deformation monitoring caused by geological disasters such as earthquake.
