About the paperAbstract
Weekly time series of geocenter motion for 1993.02006.0 obtained at INASAN DORIS Analysis center and daily GPS time series of geocenter motion for the same time interval obtained at JPL were investigated with the aim of developing mathematical model for geocenter motion. In order to estimate linear trend, amplitudes, periods and phases of geocenter variation, the methods of linear regression and harmonic analysis were applied. The evaluated amplitudes of annual variations defined by different spectral analysis methods are in a good agreement with each other. Their values vary from 57 mm for and components and 2729 mm for Z component. The first attempt to develop a mathematical model of the geocenter motion was made using the approach for spectral analysis of the long set DORIS and GPS measurements named "The Dynamic Regression Modeling (DRM)". This approach allows to predict geocenter motion for the next 1025 weeks for DORIS system and 620 weeks for GPS.
