We plan to develop a geodetic VLBI capability to provide independent confirmation of results from alternative techniques such as GPS and SLR and allow us to characterise and remove the systematic errors inherent in these systems, to produce an optimum, unified terrestrial reference system based on VLBI measurements, together with GPS/SLR data, especially for the Antarctic region. The ITRF is based on the VLBI ICRF linking our astrometric and geodynamic research programs.
We will estimate motion at sites from the combination of VLBI, GPS, gravity and tide gauge data for geodynamic effects, such as post-glacial rebound and tectonic motion, global mean sea level change and determine length-of-day (LOD) variations, focused primarily on understanding the contribution from the Southern Oceans.

Summary
A Gigabit per second Data Recording System for Geodesy and Astronomy. We plan to acquire a gigabit per second digital data recorder for geodesy and astronomy. We will develop a geodetic VLBI capability to provide independent confirmation of results from alternative techniques such as GPS and SLR and allow us to characterise and remove the systematic errors inherent in these systems.

We will increase the density of southern radio sources used to define the International Celestial Reference Frame and investigate their structure and evolution. We will make high time resolution observations of young pulsars to study the phenomena of pulsar glitches and aid in the understanding of neutron star interiors.Read moreRead less
