Seeing in the dark: measuring the signature of the early Universe with low-frequency radio telescopes. This project will detect and measure the signature of the first ionising sources in the early Universe. It uses a unique intersection of information theory and analysis methodology to design and implement a method of extracting the faint neutral hydrogen signal of reionisation from complex datasets. The hydrogen structure around these first light sources will be measured using data from the Mur ....Seeing in the dark: measuring the signature of the early Universe with low-frequency radio telescopes. This project will detect and measure the signature of the first ionising sources in the early Universe. It uses a unique intersection of information theory and analysis methodology to design and implement a method of extracting the faint neutral hydrogen signal of reionisation from complex datasets. The hydrogen structure around these first light sources will be measured using data from the Murchison Widefield Array telescope in Western Australia, revealing the signature of reionisation for the first time. Measurement of this signal constrains our understanding of the large-scale evolution of the Universe, defines properties of the first generation of stars and galaxies, and expands our understanding of the full history of the Universe.Read moreRead less

Summary
Measuring the Universe’s early evolution using lunar occultations. This project seeks to measure a radio signal for the first time, using the Murchison Widefield Array telescope and a novel technique involving the Moon, to learn what luminous objects dominated the early Universe. There is an entire period in the early Universe that remains unobserved because familiar objects such as stars and galaxies have yet to form. One of the few observables from this period, and the time directly following ....Measuring the Universe’s early evolution using lunar occultations. This project seeks to measure a radio signal for the first time, using the Murchison Widefield Array telescope and a novel technique involving the Moon, to learn what luminous objects dominated the early Universe. There is an entire period in the early Universe that remains unobserved because familiar objects such as stars and galaxies have yet to form. One of the few observables from this period, and the time directly following it, is the radio signal emitted by neutral hydrogen atoms. Innovative analysis techniques may be developed and new training pathways for astronomers should be initiated. The Project aims to raise Australia’s scientific profile and engage the public, promoting astronomy by making results accessible and using the Moon as a familiar foundation.Read moreRead less

The proposed Facility comprises a Global Navigation Satellite System (GNSS) RF Signal Simulator which allows laboratory testing of new signal tracking and navigation solution algorithms, under different scenarios. Simulation of the operation of current and future GPS satellites, and of the new European GNSS "Galileo", is vital for testing new receiver designs. For example, the Facility could be programmed to generate a GPS satellite signal with user-selectable physical variations in the signal path, including the presence of RF jamming sources, high atmospheric disturbances, diffraction effects and multipath. As many of the signal variations are rare and/or unpredictable, the Signal Simulator is the only means to carry out such tests.Read moreRead less
CHAMP GPS-Altimetry. The proposed research project aims to develop a novel application for the Global Positioning System (GPS), namely the use of GPS signals reflected from sea- or ice-surfaces and received by Low-Earth-Orbiter (LEO) for determination of these surface heights. Data from the German satellite CHAMP will be used for this purpose, for selected regions in Antartica. CHAMP covers areas not visited by other remote sensing satellites.

The GPS receiving system consists of one or more signal detection components with antennas, as well as a processing device. The main objectives of the research are: the estimation of the power budget, developing techniques for system modelling, developing techniques for simultaneous reception of signals from different satellites, and processing these signals with the aim of improving the spatial resolution, development of a demonstrator system, and evaluation of the system for selected remote sensing tasks.
