Regulation 13 Certificates
Regulation 13 Certificates are a legal document which display a station coordinate and the uncertainty of that coordinate. The certificates are generally requested by Continuously Operating Reference Stations (CORS) operators as a means of providing their users with an accurate connection to the Australian Datum - the Geocentric Datum of Australia 1994 (GDA94). Geoscience Australia is appointed as a legal metrology authority under the National Measurement Act, 1960, to provide this legal chain of traceability.
