Taken from sections of the report: Geoscience Australia operates a network of continuous geodetic quality GPS receivers, on geologically stable marks in Australia, Australia Antarctic Territory and in the South Pacific. The network in Australia and in the Australian Antarctic Territory is called the Australian Regional GPS Network (ARGN). The network in the South Pacific is for the South Pacific Sea Level Climate Monitoring Program. These sites provide the geodetic framework for the spatial data infrastructure in Australia, Australian Antarctic Territory and in the South Pacific. They also provide input for the measurement of earth processes, such as crustal dynamics and sea level rise. Data from the ARGN network also contributes to the International GPS Service. It is important to isolate any local movements such as the stability of the GPS concrete pillar from actual crustal dynamics. Geoscience Australia has routinely performed Reference Mark Surveys at all GPS stations to detect any such movements. The sites are also continually maintained and upgraded with new software and hardware to ensure the continued performance of the site and to meet the user's needs. At each Antarctic site there is a tide gauge bench mark to which the tide gauge measurement of sea level is related. This bench mark is connected to other nearby marks to monitor any possible vertical movement. In addition, the tide gauge bench mark is connected to a nearby 'Continuously Operating GPS Reference Station', to link the measurement of sea level with the ellipsoidal height accurately measured by GPS.
