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
Skycontrol 2: Long-range positioning of aircraft using multibase GPS and INS. This extends our ARC linkage project (LP0347509) by one year, where we developed and tested a long-range airborne GPS (global positioning system) using a network of ground-based receivers. While the original objectives have been met, and exceeded in some instances, we have now identified the real need to use complementary positional information from INS (inertial navigation systems). As well as reducing the cost of ai ....Skycontrol 2: Long-range positioning of aircraft using multibase GPS and INS. This extends our ARC linkage project (LP0347509) by one year, where we developed and tested a long-range airborne GPS (global positioning system) using a network of ground-based receivers. While the original objectives have been met, and exceeded in some instances, we have now identified the real need to use complementary positional information from INS (inertial navigation systems). As well as reducing the cost of airborne mapping surveys in Australia, our SkyControl2 system will have the added benefit of increased accuracy and reliability.Read moreRead less
A system for long-range positioning of airborne mapping sensors using a multi-receiver, Internet-compatible GPS network. This project will research, develop and test a GPS-network-based system, SkyControl, for the accurate coordination of airborne mapping sensors. A ground network of GPS receivers will be established and the aircraft positioned at long ranges (100 km) using a network solution, as opposed to the single-baseline solutions used at present. The GPS data from the ground network wil ....A system for long-range positioning of airborne mapping sensors using a multi-receiver, Internet-compatible GPS network. This project will research, develop and test a GPS-network-based system, SkyControl, for the accurate coordination of airborne mapping sensors. A ground network of GPS receivers will be established and the aircraft positioned at long ranges (100 km) using a network solution, as opposed to the single-baseline solutions used at present. The GPS data from the ground network will be transferred to a central location via the Internet and stored in an intelligent database so as to allow efficient data management and processing. This approach will ultimately reduce the cost and increase the reliability of airborne surveys in Australia and overseas.Read moreRead less
Theoretical and Model Strengthening of Future Global Navigation Satellite Systems (GNSS) to Yield Improved Geospatial Information for Tomorrow's Society. Australia is a significant user of Global Navigation Satellite Systems (GNSSs) because of its utility and for scientific applications (e.g., Earth-, atmospheric- and space-science). The national benefit of improved integer-estimation and model strengthening of integrated GNSSs is twofold: 1. all future scientific GNSS studies will rest on more ....Theoretical and Model Strengthening of Future Global Navigation Satellite Systems (GNSS) to Yield Improved Geospatial Information for Tomorrow's Society. Australia is a significant user of Global Navigation Satellite Systems (GNSSs) because of its utility and for scientific applications (e.g., Earth-, atmospheric- and space-science). The national benefit of improved integer-estimation and model strengthening of integrated GNSSs is twofold: 1. all future scientific GNSS studies will rest on more reliable positioning and related solutions, and 2. the refinements to these high-precision and high-integrity scientific GNSS applications will feed into much-improved geospatial information for tomorrow's society.

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.

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
