Key Researchers

Global Navigation Satellite Systems

Andrew Dempster

Professor Andrew Dempster is Director of the Australian Centre for Space Engineering Research (ACSER) at the University of New South Wales (UNSW). He is also Director of Research in the School of Surveying and Geospatial Engineering and Director of Postgraduate Research in the Faculty of Engineering. He has a BE and MEngSc from UNSW and a PhD from University of Cambridge in efficient circuits for signal processing arithmetic.

Andrew was system engineer and project manager for the first GPS receiver developed in Australia in the late 80s and has been involved in satellite navigation ever since. His current research interests are in satellite navigation receiver design and signal processing, areas where he has six patents, and new location technologies. He is leading the development of space engineering research at ACSER.

Chris Rizos

Professor Chris Rizos is currently Head of the School of Surveying and Geospatial Engineering at the University of New South Wales, Sydney, Australia. Chris has been researching the technology and applications of GPS since 1985, and established over a decade ago the Satellite Navigation and Positioning group at UNSW, today the largest academic GPS/GNSS and wireless location technology research laboratory in Australia.

Chris is the Vice President of the International Association of Geodesy (IAG), and a member of the Executive and Governing Board of the International GNSS Service (IGS). Chris is currently Chair of the working group developing the strategic plan for GNSS for Australia. Chris is also an Editor-in-Chief of the Journal of Applied Geodesy, an Associate Editor of the Journal of Location Based Services, and a member of the editorial boards for five other navigation/GPS/GNSS journals and magazines. He is an author/co-author of over 500 journal or conference papers.

Earth Observation

Linlin Ge

Dr. Linlin Ge upon graduating with a Ph.D. from The University of New South Wales, won an ARC Postdoctoral Fellowship (2002-2004), that allowed him to ramp up research into differential Interferometric Synthetic Aperture Radara (DInSAR) for ground deformation monitoring. In 2004 he was appointed at the position of Senior Lecturer in the School of Surveying and Geospatial Engineering. Linlin is leader of the CRC for Spatial Information project 4.2 "Digital Elevation Model Generation & Differential Synthetic Radar Interferometry".

As from 1 January 2008 Linlin Ge was appointed Associate Professor to support CRC-SI and NSW Dept. of Lands projects.


Sean O'Byrne

Dr. Sean O'Byrne is a Senior Lecturer at the University of New South Wales, Australian Defence Force Academy. After completing his PhD in 2002, he worked at NASA Langley Research Center on supersonic combustion until 2004. Since that time he has been working at UNSW@ADFA on the application of laser-based measurements to high-speed flows, using the T-ADFA free-piston shock tunnel facility.

Sean was the UNSW lead researcher for the University of Queensland-led SCRAMSPACE hypersonic flight test project, funded in 2010 under the Australian Space Research Program. As part of that project, he is developing an inlet sensor capable of measuring air speed and temperature in the inlet of a hypersonic vehicle, which will provide an important part of the engine control system for scramjet-powered vehicles. His other research interests include the development of sensors for commercial aircraft and exhaust emissions monitoring.

Neil Mudford

Dr. Neil Mudford has been a UNSW academic since 1989 and is a Senior Lecturer and a Deputy Head of School with the School of Engineering and Information Technology at the UNSW@ADFA campus. His research interests are focussed around ground testing in hypersonic flows. Particular interests in this area include the role of gas phase and surface catalysed chemical reactions in moderating or enhancing surface heat flux to spacecraft on atmospheric entry.

Recently, he and colleagues at the University of Queensland have developed a novel method for studying the radiative, reacting and outgassing behaviour of ablative thermal protection systems in high enthalpy hypersonic wind tunnels in flows in which the shock layer gas phase chemical reactions are also simulated at the current state of the art. Another recent development in which he is playing a leading role is the technique of releasing free-flying models into high and low enthalpy hypersonic wind tunnel flows with the aims of studying base flows and determining aerodynamic coefficients free of interference from the sting or suspension wires present in standard model support systems. Other research by Dr. Mudford is in the air-breathing hypersonic propulsion Supersonic Combustion Ramjet (SCRAMJET) and shock/boundary layer interaction.

Andrew Neely

Associate Professor Andrew Neely began his professional career in jet engine research and development for Rolls-Royce at the University of Oxford after finishing a PhD in hypersonic ground testing in Australia. He is now based in the School of Engineering and Information Technology at the UNSW@ADFA campus where he is currently a Deputy Head of School. His primary research focus within the related fields of high-speed flow and propulsion has been in the development and application of facilities and techniques to measure and predict the critical heat transfer processes that result from high energy flows, whether they be on the outside of hypersonic vehicles or internal to jet engines. He continues to work on a number of hypersonic flight test programs with DSTO and other international agencies. He has also been developing novel thrust vectoring systems for rockets and air-breathing aircraft.
