Abstract
A VLBI survey at 2.29 GHz has been conducted using a 275-km baseline consisting of the NASA DSN tracking site in Tidbinbilla, Australia, and the 64-m antenna located at Parkes, Australia, The purpase of this survey was to identify sources in the southern sky possessing strong compact cores (<.0.1 arcseconds). Such sources will be used to forma reference frame for conducting VLBI geodesy experiments in the southern hemisphere. The 70 candidate sources were chosen to be south of -39 degrees declination, and only four had been previously observed from the northern hemisphere. Of the observed: sources, 49 were- found to have compact structure. In addition to determining correlated flux densities, the delay and delay rate observables of several detected sources were used to determine an estimate of the three-dimensional location of the Parkes antenna relative to the Tidbinbilla site with a l-sigma accuracy of < 10 meters.
