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
Quantifying the flux of fugitive greenhouse gasses associated with coal seam gas and calibrating it to natural baseline and anthropogenic sources. Recent studies show that fugitive methane emissions associated with coal seam gas extraction pose a source of greenhouse gasses. In addition to the possible environmental impacts of methane emissions, quantifying the magnitude of emissions has potentially significant implications for future tax liabilities that could change the economics of the unconv ....Quantifying the flux of fugitive greenhouse gasses associated with coal seam gas and calibrating it to natural baseline and anthropogenic sources. Recent studies show that fugitive methane emissions associated with coal seam gas extraction pose a source of greenhouse gasses. In addition to the possible environmental impacts of methane emissions, quantifying the magnitude of emissions has potentially significant implications for future tax liabilities that could change the economics of the unconventional energy boom in Australia. The proposed research by an interdisciplinary team representing regulators, industry, and university researchers would establish a methodology for quantifying the flux of methane from gas fields. It would establish the range of natural baselines and determine the major sources of methane emissions using newly available highly sensitive instruments.Read moreRead less
