First, the IDS Combination Center (IDS CC) will present the latest results of the evaluation of the operational multi-satelliteseries from the IDS Analysis Centers. The evaluation will address the analysis of both the Helmert parameters of the series with respect to ITRF2014 and the Earth rotation parameter differences with respect to the IERS C04 series.
Second, the IDS CC will show the research activities he conducted mainly from the feedbacks from the IERS Production Centers on the IDS contribution to ITRF2014. These activities include analysis of the station position performance degradation between 1993 and 2002.
