DORIS is one of the far geodetic techniques (VLBI, SLR, GPS and DORIS)used by the IERS to maintain the International Terrestrial Reference System. These techniques allow the determination of the precise and regular positions of the 57 stations of the permanent network. The temporal evolution of these station coordinates allow us to access indirectly to the geocenter motion. One the objectives of the thesis is to characterize the systematic errors linked to the determination of the TZ geocenter translation. A frequency-time analysis of the geocenter time series DORIS/IGN (1993.0 to 2008.0) has pointed out the main peaks at 118 days an 1 year period (25 mm) while the annual signal obtained through the other geodetic techniques and those predi...
