Heritage recording documents archaeological sites for the benefit of future research and also to assess site degradation. This project combines the latest laser scanning technology, available through the ARC-funded LASCAN consortium, with satellite-based and digital photogrammetric survey techniques to develop a unique methodology for precise 3D recording of such sites. Records of archaeological test sites in Greece will contain unprecedented detail, comprising point clouds of greater than five million individual measurements, and spectral information in the infrared and visible wavebands. The large volume of data collected will be managed in a specially designed spatial database, accessible to the general public.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.

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

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

This project aims to realise real-time kinematic precise orbit and attitude determination of nano satellites. Formation flying, based on distributed miniaturised satellites such as Cubesats, is envisioned to revolutionise the way the space-science community conducts autonomous missions. The project will develop a purely kinematic concept exploiting the full capabilities of Global Navigation Satellite Systems (GNSS) carrier-phase measurements for instantaneous precise orbit and attitude determination of the Cubesats. The project will also pioneer the use of the satellite based augmentation systems (SBAS), supporting the future Australian SBAS program, and the development of integrated algorithms for space-based, Precise Point Positioning with fixed ambiguities supported by SBAS.Read moreRead less

This project aims to develop a holistic approach for reliable positioning for Intelligent Transport Systems (ITS). This project will address the challenges of integrity monitoring in ITS when using satellite-based technology, its integration with other sensors, and when supported by the proposed Australia National Positioning Infrastructure. It will consider Australian geography, large area, and sparse population, and emphasise rural transport. Expected primary outputs include algorithms, a detailed analysis of required systems and recommendations that will help prepare Australia for the importation of self-driving vehicles.Read moreRead less
Quality controlling GPS estimated atmospheric water vapour via stochastic modelling. Signals from satellites of the Global Positioning System (GPS) can be used to estimate the quantity of atmospheric water vapour. Such information is vital to meteorologists for numerical weather prediction, since lack of atmospheric water vapour knowledge is a significant source of error in short term (0-24 hours) forecasts of precipitation. However, to be of practical use in numerical weather models, the estima ....Quality controlling GPS estimated atmospheric water vapour via stochastic modelling. Signals from satellites of the Global Positioning System (GPS) can be used to estimate the quantity of atmospheric water vapour. Such information is vital to meteorologists for numerical weather prediction, since lack of atmospheric water vapour knowledge is a significant source of error in short term (0-24 hours) forecasts of precipitation. However, to be of practical use in numerical weather models, the estimate of the water vapour content must be accompanied by a realistic, reliable quality indicator. Such quality indicators are not currently attainable using existing GPS data processing methods, with this project aiming to overcome such deficiencies.Read moreRead less

Ellipsoidal physical geodesy - improved global and local gravity field modelling. Improved techniques for gravity field modelling, using the ellipsoidal approach proposed in this research, will increase the accuracy of the Australian geoid model.

Improved techniques for gravity field modelling, using the ellipsoidal approach proposed in this research, will increase the accuracy of the Australian geoid model. A more accurate model of the geoid will bring great cost-benefits mainly to the Australian surveying, mapping and exploration community. For example, height determination from GPS [Global Positioning System] or similar satellite-based measurements is only possible with the aid of an accurate geoid model. This will allow the use GPS to its full capacity and save valuable time and money (by as much as a factor of 10).Read moreRead less
Lunar crustal structure from high-res gravity, topography, and seismic data. This project aims to improve our knowledge of the Moon, including its surface processes, interior structure, modification by geological processes and creation and evolution. The Moon preserves the longest and cleanest records of surface geology in the Solar System’s history, unlike the Earth.

This project aims to improve our knowledge of the Moon, including its surface processes, interior structure, modification by geological processes and creation and evolution. The Moon preserves the longest and cleanest records of surface geology in the Solar System’s history, unlike the Earth. The lunar crust should exhibit strong heterogeneity in density (both porosity and composition) given its complex history of impact bombardment and volcanism. This project aims to determine radial and lateral heterogeneity in density and porosity within the Moon's crust, by analysing Gravity Recovery And Interior Laboratory gravity and spacecraft tracking data, Lunar Orbiter Laser Altimeter topography and in situ Apollo seismological data.Read moreRead less

This project will develop a new technique for isostatic analysis, using the two-dimensional wavelet transform. This tool can resolve spectral components of geophysical data in the space domain, thus avoiding the problems arising during the conventional Fourier analysis. With innovative processing methods, maps of the crustal thickness from gravity and topography data can be generated, a task usually reserved for costly seismic experiments. Analysis of the wavelet power spectrum would also benefit the exploration industry by identifying previously unknown sedimentary basins.Read moreRead less
