Local survey metadata form
In the scope of the activity of the IAG working group WG 1.2.1 Methodology for surveying geodetic instrument reference points (joint with IERS), co-location site survey and survey product metadata are being collected. Please fill the following form when sending any new survey SINEX file to the ITRF product center. Note that filled information is planned to be available online to the users of the survey SINEX files.

Local Ties used in ITRF2014
The local ties in co-location sites used in the ITRF2014 combination are in the form of SINEX files, available here:
Local ties SINEX files
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 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:
