| Zusammenfassung |
| This paper will address key questions regarding the ITRF2013
elaboration: frame specifications (origin, scale, orientation
and their time evolution) and how they will relate to ITRF2008;
non-linear station motions (seasonal signals and post seismic
deformations) and how they will be modeled; local ties and
station co-motions and how they will be weighted, taking into
account technique discrepancies at co-location sites. A
particular emphasis will be given to assess the stability of
SLR origin as well as SLR and VLBI scales over the entire
observation history of both techniques. To answer these
questions, early submissions to ITRF2013 of technique solutions
will be analyzed, otherwise operational technique products will
be used instead. |
