CORSnet-NSW reaches 150 CORS milestone

CORSnet-NSW is Australia's largest owner-operated Global Navigation Satellite System (GNSS) Continuously Operating Reference Station (CORS) network. It is built, owned and operated by Land and Property Information (LPI), a division of the Office of Finance and Services, NSW Treasury. LPI's first CORS was installed in 1992 in Bathurst, using in-house developed programming to support internal survey and aerial photography operations. In 2004, a pilot-project network of seven CORS was installed in the Sydney metropolitan area and made available to the public one year later under the name SydNET. A renewed effort of expansion to extend the coverage of CORS throughout NSW commenced in 2009 as part of a 5-year, multimillion-dollar Survey Infrastructure Improvement Project, which corresponded with the rebranding of the network as CORSnet-NSW. In only four-and-a-half years, the network has grown from 27 stations in late 2009 to 150 CORS in July 2014... and it still keeps on growing. Trimble ranks CORSnet-NSW in its top 10 CORS networks in the world. This article provides a brief overview of the current status of CORSnet-NSW and indicates what's in store for the near future.
