Local Ties used in ITRF2008

The local ties in co-location sites used in the ITRF2008 combination are in the form of SINEX files, available here:

Local ties SINEX files

Local Ties used in ITRF2005

The local ties in co-location sites used in the ITRF2005 combination are in the form of SINEX files, available here:

Local ties SINEX files

Empirical variance factor for each one of the individual local tie solutions (SINEX files) is estimated following the procedure described in Altamimi et al. (2002)

A list of local tie vectors, together with their uncertainties as extracted from the re-scaled SINEX files, is also available here:

Local ties table

In addition, all the post-fit residuals of the ITRF2005 combination are listed in the following file: ftp://igs.ensg.ign.fr/pub/igs/itrf2005/ITRF2005-RES.DAT
