AB: Using various time series of sets of station coordinates derived from satellite geodetic observations, we describe the motion of the Earth's geocenter by the time series of the origin of the individual data sets in a common reference frame. The goal of the analysis of these time series is to extract and compare various components such as trend, seasonal and irregular components. In addition to the comparative analysis of the individual signals, a noise analysis of the series is performed. The geodetic techniques involved are DORIS, SLR and GPS, and the respective time intervals are monthly, weekly and daily.
