Abstract We use the singular spectrum analysis method to spatial filter with GAMIT/GLOBK processing of high precision CZCORS coordinate time series. To exclude common mode errors of coordinate time series, a maximum likelihood estimation method is used for noise characteristic analysis. The optimal white noise model is “WH”, the optimal colored noise model of the N, U components is “WH+FN”, and the optimal colored noise model of the E component is “WH+FN+RWN”. Employing the optimal colored noise model to estimate the regional CORS sites velocity field, shows a southeast overall movement trend, and the overall displacement value and movement direction is similar to the surrounding IGS stations.
