Abstract
The new Australian geodetic VLBI network operated by the University of Tasmania (UTAS)
started regular observations in June, 2011. Three 12-m "Patriot" radio telescopes (Hobart
in Tasmania, Yarragadee in Western Australia and Katherine in the Northern Territory) are
dedicated to the improvement of the celestial and terrestrial reference frames in the southern
hemisphere. We present first results from the analysis of a 16-month set of geodetic VLBI
data. The data were processed within a VLBI solution for 78 sessions in 2011–2012 by
the least squares collocation method using the OCCAM software. The geodetic positions
of the AuScope radio telescopes were estimated with accuracy less than 10 mm, and
the first sign of their motion due to tectonic plate movement was indicated. Results of
independent verification using GPS and geodetic local tie for Hobart12 showed consistency
within 20 mm for all three components. Positions of Hobart12 in the ITRF2005 system are
presented for the 2012.0 epoch.
