| Zusammenfassung |
| ITRF2013 is intended to be the next version of the
International Terrestrial Reference Frame (ITRF) to be released
by mid 2014. It will be constructed upon reprocessed solutions
provided by the Technique Centers of the four geodetic techniques
(VLBI, SLR, GPS, DORIS), and local ties at co-location sites.
To that end, we operate preparatory analysis and enhancement of
the CATREF combination software targeted towards and improved
ITRF2013 solution. Selected results of these preliminary analysis
will be presented and discussed, focusing on the accuracy of the
combined reference frame, including: impact of weighting and
selection of local ties; evaluation of the accuracy of the origin
and the scale using extended input data beyond the ITRF2008;
impact of applying non-tidal atmospheric loading corrections on
station positions, velocities and Earth Orientation Parameters. |
