The provision of access to a nationally coordinated CORS network
Paull, Dan
How can Australia achieve national coordination of its Global Navigational Satellite Systems (GNSS) Continuously Operating Reference Station (CORS) networks and thus capitalise on the current and future investment into this vital infrastructure? Does a key part of that national solution include a broker who facilitates access to all CORS data? If so, can such an approach provide data of sufficiently high quality (even government assured) and within a business model that encourages participation? This paper will be exploring these questions, as well as the complex environment driving the development of a nationally coordinated CORS network. GNSS CORS networks providing observation corrections to a rover receiver via a communication link enable real-time kinematic (RTK) positioning at the centimetre level. Such CORS networks are beginning to develop in pockets across the country where efficiency gains are driving their implementation in a variety of disciplines including agriculture, mining, construction, transportation and aviation. At this stage, however, there is no coordination of this investment between infrastructure owners and no mechanism in place that would facilitate what would effectively be a national CORS network.
