Abstract Aiming at analyzing the coordinate time series of crustal movement observation network of China (CMONOC), this paper explores the effect of three reference frames of different size and two kinds of similarity transformations with different transformation parameters on velocity field, annual term and residual position time series of the stations. On the basis of these solutions, for a long-term continuously observed GPS network covering a large area such as the Chinese mainland, a global reference frame makes the analysis results of the coordinate time series more stable and less sensitive to transformation parameters. By contrast, selecting a regional reference frame, especially one covering an area closer to the studied region, can present more information of regional deformation which aids in the study of the dynamic mechanism of this deformation.
