| Abstract: | As an Associate Analysis Centre for the MERIT campaign ESOC has processed the complete data set of LAGEOS laser ranging normal points for the 14 months period of the campaign (September 1983 to October 1984), using independently developed software. Geocentric coordinates have been obtained for a network of 20 laser stations, and series for the pole, UT1R and length of day have been derived with 5 day resolution. Discrepancies in the node and inclination estimates between successive monthly arcs are attributed to mismodelled tidal effects. Detailed comparisons have been made with solutions obtained at other processing centres based on VLBI and SLR techniques. |
