Defining and developing a marine cadastre for Australia. Australia's ocean territories cover an area 1.5 times larger than the nation's land mass. Systems for the management and administration of land in a spatial context have been developed over many years but no such system exists for the nation's oceans. A marine cadastre aims at providing a comprehensive spatial data infrastructure and spatial analysis tools for the assessment, administration and management of rights, restrictions and respo ....Defining and developing a marine cadastre for Australia. Australia's ocean territories cover an area 1.5 times larger than the nation's land mass. Systems for the management and administration of land in a spatial context have been developed over many years but no such system exists for the nation's oceans. A marine cadastre aims at providing a comprehensive spatial data infrastructure and spatial analysis tools for the assessment, administration and management of rights, restrictions and responsibilities in the marine environment. The objective of this project is to investigate the issues and define the problems associated with the development of a marine cadastre, thereby providing the foundation for future research.Read moreRead less

Investigations of the Integrity of the Australian Height Datum. The Australian Height Datum (AHD) forms the fundamental framework for all vertical spatial information in Australia. It supports a wide range of applications in areas such as geodesy, surveying, mapping, telecommunications, resource exploration and environmental science. This medium-term research programme will investigate the many issues surrounding the integrity of the AHD, and will rigorously redefine, correct and unify it with ....Investigations of the Integrity of the Australian Height Datum. The Australian Height Datum (AHD) forms the fundamental framework for all vertical spatial information in Australia. It supports a wide range of applications in areas such as geodesy, surveying, mapping, telecommunications, resource exploration and environmental science. This medium-term research programme will investigate the many issues surrounding the integrity of the AHD, and will rigorously redefine, correct and unify it within a global vertical framework. This will provide improved height information to the numerous users of the AHD in Australia, and allow Australia to contribute more fully to the global spatial data infrastructure.Read moreRead less

This interdisciplinary project develops a highly novel total network strategy for real-time kinematic GPS positioning services using the Internet communication protocols for data transmission. The proposed system is technically superior to existing network-based differential GPS (DGPS) systems, by providing positioning services at different accuracy levels (metre to centimetre) with reduced operational cost to users. The research focuses on improved network operations and processing, along with developing user-specific algorithms. The outcomes are expected to provide significant opportunities for both real time and near-real-time kinematic positioning applications and commercialisations of such services, in urban and regional areas of Australia.Read moreRead less
Real-time atmospheric modelling for centimetre-level positioning based on Global Navigation Satellite System (GNSS) continuously operating reference station networks. Many applications of Global Navigation Satellite System (GNSS) technology, such as surveying, mapping and precise navigation, require real-time positioning accuracies to centimetre levels.

Many applications of Global Navigation Satellite System (GNSS) technology, such as surveying, mapping and precise navigation, require real-time positioning accuracies to centimetre levels. To support these applications, many countries are establishing dense networks of continuously operating reference stations, positioned typically less than 40 km apart. However, for Australia with its large and sparsely populated regions, these dense networks cannot be justified economically. Our project will investigate appropriate enhancement of sparse networks to maintain the same level of accuracy. It will focus on a better understanding of atmospheric conditions, currently a major limitation in the development of sparse networks.Read moreRead less
Next generation global navigation satellite systems ambiguity resolution. In the next five years, four new satellite-based navigation and positioning systems, called Global Navigation Satellite Systems (GNSS), will come to challenge/complement the well-known US global positioning system (GPS). In order to get the highest accuracy and most reliable results from these GNSSs, a procedure known as ambiguity resolution (AR) is essential. This collaborative project will bring Professor Peter Teuniss ....Next generation global navigation satellite systems ambiguity resolution. In the next five years, four new satellite-based navigation and positioning systems, called Global Navigation Satellite Systems (GNSS), will come to challenge/complement the well-known US global positioning system (GPS). In order to get the highest accuracy and most reliable results from these GNSSs, a procedure known as ambiguity resolution (AR) is essential. This collaborative project will bring Professor Peter Teunissen, the inventor of the famous LAMBDA method that is currently used in all GPS AR software, to Australia to work on AR for a combined new GNSS AR solution that is also optimised for Australian users.
