AuScope is part of the Australian Government's National Collaborative Research Infrastructure Strategy (NCRIS) and has the objective of upgrading the accuracy of the terrestrial reference frame in Australia to 1 mm based on the development of new geodetic infrastructure which for example includes three new Very Long Baseline Interferometry (VLBI) observatories and 100 Global Navigation Satellite System (GNSS) stations. Each of the AuScope VLBI observatories, located at Hobart, Yarragadee and Katherine, are equipped with a 12.1 metre antenna designed and constructed by COBHAM Satcom, Patriot Products division. In a preliminary multi-technique inter-comparison, GPS data have been analysed in the Bernese software and VLBI and local tie data have been analysed in the in-house developed software OCCAM and Axis, respectively. Our experiences and techniques for undertaking local tie surveys of the Patriot antennas are overviewed, and results of the GPS, VLBI and local tie inter-comparison are presented.
