How does it work?

The service is delivered by a network of permanent GNSS receivers, known as Continuously Operating Reference Stations (CORS), that are strategically located across NSW.

The CORSnet-NSW network continuously observes and corrects satellite navigation signals in order to achieve international-standard, high-accuracy positioning data for NSW (JPG 329.6 KB).

The data is streamed to users via a wireless internet connection. CORSnet-NSW supports both GDA2020 and GDA94 positioning services.
