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
Real-Time Integration of GPS with INS For Precise Long-Baseline Kinematic Positioning. 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 ....Real-Time Integration of GPS with INS For Precise Long-Baseline Kinematic Positioning. 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
