Next generation datum (1.02)
The objective of a new National Positioning Infrastructure (NPI) is to provide real-time, centimetre-level positioning services regardless of location. In support of this objective, this project is developing the geodetic techniques, tools and standards required to implement the next generation geodetic datum which will underpin the NPI.
This project will help government participants to develop and implement a smooth and robust transition to a next generation datum in Australia and New Zealand. Its outputs will have significant scientific and practical impact and importantly will provide a sound scientific foundation on which to build a future datum.
The project focuses on terrestrial reference frames (ie geometric datum), 4-D (dynamic) coordinate estimation and modelling strategies, and the regulatory and administrative impediments to implementation of dynamic datum.
- “Impact of a Next Generation Geodetic Datum” forum was held at the SSSI Conference, Canberra, on 19 April
- “Impact of a Next Generation Geodetic Datum for the Northern Territory” forum was held in Darwin, NT, 29–31 May
- “Reference Frame in Practice Technical Seminar” at the South East Asian Survey Congress (21-22 June) in Manila, The Philippines
- Progress on running the Dynanet software on the National Computational Infrastructure, and testing on large network adjustments
- The ICSM’s Permanent Committee on Geodesy (PCG) met in Canberra, 15-19 April, and the CRCSI 1.02 plans have been aligned to the PCG’s work-plan regarding datum modernisation
