Grgs Evaluation Of Itrf2008, From Slr Data

As an ILRS Analysis Center (AC), we report further the official (final) ITRF2008 solution delivered by the ITRS product center. Following the operational analysis scheme of SLR data, that we perform over the period 1995-2010, we compute for the Lageos-1 and Lageos-2 satellites weekly arcs with ITRF2005 and ITRF2008. Then, we evaluate the sets of orbital parameters, of Earth Orientation Parameters (EOPs), and of Station Coordinates (SSCs). We also compare our results to those obtained by other ACs, in terms of SSCs, EOPs, translations and scale factors.
