Status of DORIS contribution to ITRF2013
Abstract
In the context of the forthcoming realization of the forthcoming of ITRF 2013, the IDS Combination Center is involved in the estimation of DORIS stations positions/velocities as well as Earth orientation parameters from DORIS data. These computations are based on the latest series of all of the 6 IDS Analysis Centers multi-satellite weekly SINEX solutions from January 1993 to December 2013. Due to some technical issues remaining on Cryosat-2: 1993 to mid-2010, and mid-2010 to 2013. The first objective of this study is to analyze the preliminary version of the DORIS contribution to ITRF2013 from 1993-2010 in terms of (1) geocenter and scale solutions; (2) stations positions. The second purpose is to compare this new DORIS ITRF realization to the previous one (for ITRF2008). Then, we will conclude by addressing latest news on the IDS actions and schedule for final delivery of the entire DORIS contribution to ITRF2013 to IERS.
