dc.description.abstractThe recent release of candidate solutions for adoption of the new ITRF2005 International Terrestrial Reference Frame (ITRF) initiated numerous tests and comparisons over the past months. This presentation focuses on the evaluation tests we performed with the ITRF2005P and ITRF2005D products, primarily with Satellite Laser Ranging (SLR) tracking data. Since over two decades now, SLR tracking data contribute to the definition of the TRF, primarily in defining its origin and scale. LAGEOS 1 and 2 are the main targets contributing to this, and we use their data, as well as a limited number of independent data to gauge the improvement gained by going from ITRF2000 to either of the two new candidate solutions. An easy and immediate observation is that either of them is only slightly different from ITRF2000, in contrast to what was observed during the release of ITRF2000. This seems natural though, since ITRF2000 dealt with many problems observed with its predecessor and used a uniformly high quality input from nearly all techniques. We concentrate here on the differences between the two and the impact of such factors as the improvements in the analysis methodology, the underlying models, the use of IERS Conventions 2003, and the latest improvements in modelling SLR observations.en_US
