CORSnet-NSW is a network of Global Navigation Satellite System (GNSS) continuously operating reference stations (CORS) that will cover New South Wales and is an expansion of SydNET, which has been successfully operating in the Sydney metropolitan region since 2004. CORSnet-NSW is fully funded and managed by Land and Property Information (LPI), a division of the NSW Land and Property Management Authority (LPMA). In excess of seven million Australian dollars have been committed for capital investment in the Survey Infrastructure Improvement Project – the majority of which will be invested in the CORS network – plus additional recurrent funds to operate the network. CORSnet-NSW currently (January 2010) consists of 29 CORS and is being expanded to include 70 stations by 2013 in order to provide state-wide coverage. As part of this expansion, LPI has purchased Trimble Navigation’s VRS3Net CORS network management software which will significantly enhance the range and quality of services that LPI can provide to its customers. Work is being undertaken to integrate VRS3Net with LPI’s existing accounting and delivery systems, which is a first for this system. Currently, dual network control centres are being built at LPI’s data centres in Sydney and Bathurst. Once completed, these control centres will provide a fully redundant network with ample capabilities for many years to come. This new infrastructure will also facilitate a wide range of research projects in the areas of geodesy, surveying, positioning, navigation and telecommunications. CORSnet-NSW will provide users with network real time kinematic (NRTK) services in the extended Sydney metropolitan area as well as other populated regions of the state and singlebase RTK elsewhere, as well as supplying GNSS data for post-processing. RTK and NTRK correction data are available in RTCM 3.1 format via the internet using NTRIP (Networked Transport of RTCM via Internet Protocol), providing centimetre-level horizontal positioning in real time. This paper introduces CORSnet-NSW and discusses several issues that need to be addressed in order to provide a reliable GNSS positioning service of homogeneous and high accuracy across the state. These issues include the direct connection to the national datum, legal traceability of CORS coordinates, compatibility with online GNSS processing services and CORS networks in neighbouring states, and the correct use of Antenna Phase Centre Variation (APCV) models.
