Abstract
Based on the time series of station coordinates provided by international SLR service (ILRS) over 1993–2011 using a set of global 92 ILRSA fiducial stations and by international VLBI service (IVS) over 1980–2009 using a set of global 113 VLBI fiducial stations, we generated a time series of the geocenter motion (GCM) and scale factor variations in terms of the network shift approach, which has been the longest and highest accurate one until now. Fourier analysis and wavelet analysis were employed to analyze the nonlinear variations of GCM and scale factor time series. The results indicate that the variations of GCM and scale are dominated by annual and semiannual motions, and show certain long periodic variations. The amplitude and phase of the annual and semiannual motions has certain changes in different years.
