The national measurement system in Australia ensures a basis for legally traceable, consistent and internationally recognised measurements. With the growing societal dependency on GPS, the need for the legal traceability of GPS positions with respect to the Australian Datum - the Geocentric Datum of Australia 1994 (GDA94) -- has become increasingly apparent. In the interest of ensuring consistency of positions derived from private and government Continuously Operating Reference Stations (CORS),Geoscience Australia maintains an appointment as a legal metrology authority in accordance with the National Measurement Act 1960 and provides legally traceable positions. This presentation will overview Geoscience Australia's approach to the legal traceability of GPS positions, the process of legal certification including: (1) the basic requirements for requesting certification; (2) quality standards and the quality management system of the position verification processes. The structured maintenance and continual improvement program for the verifying laboratory will also be introduced.
