Abstract: Australia’s National Positioning Infrastructure (NPI) Plan emphasises the importance of space-based positioning, navigation and timing as components of Australia’s smart infrastructure and social, economic and national security. This Plan proposes improved governance of positioning infrastructure, additional investment in ground infrastructure to deliver accurate and reliable positioning information to users across Australia and the development of a sovereign capability for GNSS product generation and integrity monitoring through an indigenous Analysis Centre Software (ACS). In partnership with the CRC for Spatial Information (CRCSI), Geoscience Australia is leading the development of this ACS. The objective of the ACS project is the development of a multi-GNSS, multi-frequency network processing platform and the establishment of a national positioning capability. In this presentation, we focus on the challenges of designing and developing the ACS network platform, specifically addressing PPP-RTK corrections (orbits, clocks, uncalibrated hardware delays, ionosphere models), options for delivering corrections (satellite or ground infrastructure) and the format of corrections to be delivered to the users.
