摘 要: | In GPS regional network coordinate time series, common mode errors (CME) are widespread. In order to extract CME, a sub-region is divided to get them superimposed and filtered. However, there is no principle to rely on for dividing sub-regions. According to the CME mentioned above, regarding three stations in southern California as centers, we divide the space into nine different spaces within different scales, carrying out the PCA space filtering method, to get the CME in each space scale. After analyzing and comparing the CME in each space scale, we can get the spatial response characteristics in CME, which provides a principle for the dividing sub-regions in the scale field.
