We all rely on GPS to tell us where we are and where we’re
going. The US government’s global network of 30+ satellites guides planes,
ships, cars, tractors and much more. The latest GPS systems can provide mm- to
cm-accuracy using advanced equipment and technique.
But GPS isn’t the only game in town. There are other
global systems, and regional systems that we can tap into.
Curtin University researchers have explored the potential
of regional navigation satellite systems (RNSSs) for Western Australian users.
Two such systems are the QZSS operated by Japan and the IRNSS operated by
The work of Indonesian and Australian scientists is resulting in re evaluation of Jakarta’s seismic risk by Indonesian Government agencies.
The team is scanning the Earth from thousands of kilometres in the air, right down to chemical traces found in rocks, as they hunt out telltale signs of future earthquakes and the damage they might do. They’ve highlighted a major new seismic threat for East Java as well as the tsunami threat to Bali, Lombok, Nusa Tenggara, and other coasts along the Flores Sea; and have identified active faults in the Nusa Tenggara region of Eastern Indonesia, measuring the rates of strain building up.
