Summary
A Signal Simulation Facility for GNSS Receiver Design and Testing. 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.

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
A combined inertial, satellite & terrestrial signal navigation device for high accuracy positioning & orientation of underground imaging systems. The 'holy grail' of the mapping community is ubiquitous, cm-level accuracy positioning/orientation in all outdoor environments with a minimum installed infrastructure and operational complexity.

The 'holy grail' of the mapping community is ubiquitous, cm-level accuracy positioning/orientation in all outdoor environments with a minimum installed infrastructure and operational complexity. There is currently no system able to address such needs. The integration of an Australian-developed technology within the standard GPS/inertial navigation configuration would be a truly ground-breaking achievement. This would represent a significant enhancement of Australia's capacity to develop high-value navigation products and services, and the proposed project outcomes align closely with National Research Priority 3, and address the 'Frontier Technologies and Smart Information Use' priority goals.Read moreRead less
Protecting Critical Transport Infrastructure using Hybrid Approaches for Interference and Spoofer Detection and Localisation. Modern infrastructure increasingly relies on the positioning and timing capabilities provided by the Global Navigation Satellite Systems (GNSS). GNSS signals, however, are vulnerable to interference and spoofing attacks. This vulnerability is aggravated as satellite navigation becomes more central to the operation of airports, ports, railways, and communications systems. ....Protecting Critical Transport Infrastructure using Hybrid Approaches for Interference and Spoofer Detection and Localisation. Modern infrastructure increasingly relies on the positioning and timing capabilities provided by the Global Navigation Satellite Systems (GNSS). GNSS signals, however, are vulnerable to interference and spoofing attacks. This vulnerability is aggravated as satellite navigation becomes more central to the operation of airports, ports, railways, and communications systems. Building on from earlier work by University of New South Wales, University of Adelaide and GPSat Systems, this project aims to create a system for locating interference and spoofers to GNSS of any power in real time, providing layered monitoring and reactive mitigation solutions against interference and spoofing attacks.Read moreRead less

In collaboration with University of Nottingham researchers, a bridge structure in the U.K. will be used as a testbed, and will be the first time that PLs have been used for such an application. The expected outcomes include a suite of deformation monitoring algorithms capable of online analysis of the combined GPS-PL outputs.Read moreRead less

Locating Interference to GPS: Protecting the World's Aircraft Landing Systems. GRAS is an enormous initiative that is expected to generate billions of dollars in exports for Australia. The equipment developed in this project will protect the system from radio frequency interference. It thus protects these exports, and creates a new exportable product. By protecting this system, it makes air travel safer both in Australia and in the countries that buy this Australian technology.
