| Zusammenfassung |
| Quality assessment of ITRF2008 solution has been undertaken,
indicating the well performance of ITRF2008 determination of
station positions and velocities, compared to past solutions,
including ITRF2005. As a by-product, we estimated rotation
poles for 15 tectonic plates, using a velocity field composed
of more than 250 sites with long observation history. The main
criteria selection are (1) the velocity formal error is less than
0.5 mm/yr and (2) the post fit residuals should not exceed the
threshold of 1.5 mm/yr for each site. We examine the quality of
the TRF2008 Plate Motion Model using different possible estimation
options and by comparisons to other existing models. We also evaluate
the impact of correcting or not horizontal post glacial rebound
effects before rotation pole estimation. |
