Current Results of the Earth Orientation Parameters Prediction Comparison Campaign
Abstract
The precise transformation between the celestial (ICRF) and terrestrial (ITRF) reference frames is needed for many advanced geodetic and astronomical tasks. To perform this transformation for the time moment of observation the precise EOP data and their predictions have to be known. This poster presents the current status of the Earth Orientation Parameters Prediction Comparison Campaign (EOP PCC), which started in October 2005 under the umbrella of the IERS (International Earth rotation and Reference systems Service). The ultra-short term, short term and medium term EOP predictions submitted since then by different groups/algorithms were evaluated by means of the same statistical analysis. The mean prediction errors of the EOP together with their error bars for each group/algorithm were computed with respect to IERS C04_IAU2000.62-now data to show the performance in each prediction category. The contribution of each group/algorithm for computation of the combined EOP predictions is shown.
