Although Australian researchers have played an important role in the development of carrier phase-based GPS kinematic positioning algorithms and methodologies over the last two decades, investigations concerning high precision multi-sensor integration have been comparatively limited. This ARC project would go a significant way towards remedying this situation by building up theoretical and practical expertise in sensor integration techniques at the postdoctoral level. The outcomes of this project will represent a significant contribution to Australian R&D in the fields of precise positioning and navigation, since they will be directly applicable to the design and development of a variety of integrated multi-sensor systems.Read moreRead less
Integrated GPS and interferometric SAR techniques for ground subsidence monitoring. The Global Positioning System (GPS) is commonly used for measuring ground subsidence due to underground mining and similar activities. However, GPS techniques cannot easily survey a dense enough grid of points to monitor subsidence across a wide area. This project aims to densify the GPS field measurements with the interferometric processing of Synthetic Aperture Radar (SAR) images. The outcomes of this research ....Integrated GPS and interferometric SAR techniques for ground subsidence monitoring. The Global Positioning System (GPS) is commonly used for measuring ground subsidence due to underground mining and similar activities. However, GPS techniques cannot easily survey a dense enough grid of points to monitor subsidence across a wide area. This project aims to densify the GPS field measurements with the interferometric processing of Synthetic Aperture Radar (SAR) images. The outcomes of this research include optimal integration models, operational software systems and quality-control measures. A test area south of Sydney, where subsidence caused by underground coal mining is having significant detrimental effect on surface infrastructure, will be monitored over a three-year period.Read moreRead less

Environmental geodesy: variations of sea level and water storage in the Australian region. It is essential for Australia's long-term planning and security that the effects of global warming on our nation's water resources and coastlines are quantified. Sea level variations projected into the future vary around Australia and have large uncertainties, yet the impacts have substantial social and financial ramifications for our community. Australia hasn't yet quantified accurately its critical water ....Environmental geodesy: variations of sea level and water storage in the Australian region. It is essential for Australia's long-term planning and security that the effects of global warming on our nation's water resources and coastlines are quantified. Sea level variations projected into the future vary around Australia and have large uncertainties, yet the impacts have substantial social and financial ramifications for our community. Australia hasn't yet quantified accurately its critical water resources nor how they are changing. This proposal will address both these issues, providing for the first time valuable and accurate information for planning appropriate strategies to mitigate the impact of sea level rise and water storage on the Australian society.Read moreRead less
Tracking the response of terrestrial and ocean waters to climate variations using space gravity observations. Climate change puts Australia at risk from sea level rise and an increase in the occurrence and intensity of droughts. We need to learn about issues concerning the water cycle that are still poorly understood, such as whether droughts cause a reduction in only surface water or also water stored in underground reservoirs and what happens to ocean waters when thermal expansion causes an in ....Tracking the response of terrestrial and ocean waters to climate variations using space gravity observations. Climate change puts Australia at risk from sea level rise and an increase in the occurrence and intensity of droughts. We need to learn about issues concerning the water cycle that are still poorly understood, such as whether droughts cause a reduction in only surface water or also water stored in underground reservoirs and what happens to ocean waters when thermal expansion causes an increase in sea surface height in some regions but not others. This proposal will provide new and accurate scientific information on the risks of sea level rise through the effects of thermal expansion of the oceans, in particular in shallow coastal zones. It will help us to understand droughts, variations in water resources and groundwater recharge patterns.Read moreRead less
