POLICY

The purpose of this policy is to outline a set of principles for the provision of a national positioning infrastructure (NPI) that will ensure sustainable, nationally compatible deployment of GNSS Continuously Operating Reference Stations (CORS) infrastructure capable of accommodating a variety of providers and ensuring an efficient and effective Australia wide coverage and service for the positioning needs of a diverse user community. BACKGROUND Positioning Infrastructure underpins the referencing and application of the majority of spatial data. In Australia the term “positioning infrastructure ” is used to describe a very broad array of infrastructure elements that include: Ground based survey marks. These have historically been used to realise the geodetic datum and provide user access to the resulting coordinate system. Increasingly, these survey marks are maintained for specific applications like a coordinated cadastre, or in areas where GNSS positioning is not possible. GNSS space segment. In addition to the operational systems: USA’s Global Positioning System (GPS) and Russia’s GLONASS, there are now several other Global and Regional Navigation Satellite Systems (GNSS/RNSS) proposed or under development. Galileo is a comprehensive system under development by the Europea
