Abstract：The data of the Shaanxi continuous GPS reference stations from Jan 1st ,2011 to May 30th,2013 are computed and analyzed in this article. After common mode error being removed by the regional stacking, the mean RMS of coordinate time series are declined 69%,60% and 41% respectively in N,E,U directions. The spectral indexes analysis states that the afterfiltered coordinate time series contain the white noise and the color noise . The CATS software analysis indicates that the noise components of vertical direction are much larger than those of horizontal direction,and random noise appear in some stations along with flicker noise being decreased by the spatial filtering.
