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
