- The objective of this paper is computation of the corrections to sea level anomaly data due to center of Earth mass variations. The geocenter motion model was computed from the center of mass coordinates data determined from observations of space geodetic techniques such as Satellite Laser Ranging (SLR), Global Navigation Satellite System (GNSS) and Doppler Orbitography and Radiopositionig Integrated on Satellite (DORIS). In order to compute the geocenter motion model the center of mass coordinates data were filtered using wavelet based semblance filtering which allows computing a common signal in two time series. Based on determined geocenter motion model a correction to sea level anomalies (SLA) data due to geocenter motion was determined. This kind of correction to sea level anomaly data is of the order of few millimetres and should be applied to altimetric measurements to refer them to the International Terrestrial Reference Frame (ITRF) Origin considered as the center of figure.
