GNSS is used to define, maintain and connect to the International Terrestrial Reference Frame (ITRF). SNAP Lab research builds on decades of geodetic expertise, and includes: the new positioning datum for Australia & New Zealand; ground deformation monitoring; and GNSS network data processing algorithms.
SNAP Lab has designed the “Namuru” GNSS receivers to track today's and tomorrow's GNSS signals. GNSS signal processing is expanding area of research and includes radio-frequency interference detection & geolocation, time synchronisation of receivers, weak GNSS signal tracking, and GNSS remote sensing using reflectometry and radio occultation techniques.
GNSSs, such as the US’s GPS, Russia’s GLONASS, Europe’s Galileo and China’s BeiDou, have many applications: land, air & maritime navigation; military & security-related operations; agriculture, mining & construction; geodesy, surveying & mapping; machine automation & robotics; transportation; timing; and personal location-based services – all using different receiver instrumentation, infrastructure, operational procedures and measurement processing.
Positioning inside buildings, supporting the blind and visually impaired, underground mine systems, etc; using different technologies, including WiFi, RFID, vision and inertial sensors. SNAP Lab has helped develop the Australian Locata system, a high accuracy positioning technology able to be used on its own or in combination with GNSS.
Multi-sensor integration research includes the classical combination of GNSS with an Inertial Navigation System, to provide sensor platform positioning and orientation information; for satellites, unmanned aerial vehicles (UAVs) and terrestrial platforms. SNAP Lab has a long heritage in multi-sensor navigation system research.
For surveying, geodesy, structural monitoring, geo-referencing of moving platforms, support for robotics & machine guidance, and cooperative positioning in support of advanced transport applications. Research areas include: measurement modelling & algorithms; multi-GNSS systems; Precise Point Positioning; differential positioning; impact of augmentation services; design of reference station networks & protocols; and multi-sensor integration.
Staff and students from the Schools of Civil & Environmental Engineering and Electrical Engineering & Telecommunications conduct cross-disciplinary research into Positioning and Navigation technologies and applications – ranging from satellite systems such as GPS to ground-based systems, and multi-sensor integrated systems. Applications range from geodesy, surveying and navigation, to mass market location-based services, personal navigation and intelligent transport.
