Comments:
†   —   velocity is not measured, but taken from the geophysical model NUVEL-NNR. The estimate of uncertainty, 3.0 mm/yr, is a speculation based on the deviation of velocities of other VLBI stations from the NUVEL-NNR.
‡   —   velocities of DSS45 and TIDBIN64 were constrained to be equal.

Solution pet2008c was produced using all available VLBI observations in geodesy and/or absolute astrometry from 1980.3 through 2008.6, in total 6.4 million observations, including two geodesy/astrometry LBA experiments in 2007-2008. Solution pet2008c proviudes absolute positions. It does not have a net translation and net rotation with respect to the ITRF2005 station position catalogue, and therefore, it is consistent with that catalogue.

These positions are tied to the position of CATW104 (also known a ATCA-104) from pet2008c solution. A linear velocity should be taken into account for computing positions of the antenna reference point at the epoch of interest:
