By collecting geodetic data from Global Navigation Satellite Systems (GNSS) at Continuous Operating Reference Stations (CORS), Geoscience Australia is able to measure the relative locations of points up to several thousand kilometres apart with an accuracy of several millimetres. As such, the Australian Regional GNSS Network (ARGN) operated by Geoscience Australia, is the national foundation for all positioning applications in Australia.
However, this network is sparse and tells us little about intraplate deformation and the resultant neo-tectonic strain. In addition, it does not provide good proximity for the many surveying applications that use the ARGN data.
The AuScope GNSS network which will be implemented by Geoscience Australia and the state and territory governments is designed to distribute GNSS stations along transects with a nominal spacing of 200 kilometres. Researchers will be able to monitor the deformation of the Australian continent in greater detail in near real-time, and the benefits of such a high-accuracy reference system will flow through to other areas of geoscientific research.
