Abstract：By using the GAMIT software and the data of Liyang, Nantong and Yancheng GNSS observation stations, the paper calculates the displacement time series of Liyang, Nantong and Yancheng GNSS observation stations in Jiangsu province from June 2010 to August 2013 based on the GPS positioning principle. The results show that: among these years, the three GNSS stations move to the southeast direction; they have permanent coseismic displacement caused by the earthquake occurred in March 11 of 2011 in Japan;the observation data in NS, EW and the vertical direction of these three stations show better annual variation. This is the preliminary application of GNSS data in Jiangsu earthquake precursor monitoring, and also provides a new means for earthquake prediction research of Jiangsu area.
