A pair of spatial science researchers have completed the first research in Australia to integrate Global Positioning System (GPS) technology with the emerging Galileo satellite system in a project funded by the Australian Space Research Program.
Curtin Universitys Professor Peter Teunissen and the Western Australian School of Mines (WASM) Dr Dennis Odijk have demonstrated how the two systems can be combined. Their research combined real-time data collected using high-grade multi-Global Navigation Satellite System (GNSS) receivers from different manufacturers for baselines studies in Australia and the US.
Galileo is being developed by the European Union and is a complete new multi-frequency GNSS. It is in a testing phase, and is planned to have 30 satellites in full operation by 2018. It was selected for this research as it is expected to be one of the most commonly used systems, and because it operates on the same frequency as GPS.
To date, the GPS has been the best known and only fully operational system. According to the university, the new capability is becoming essential as a growing number of next-generation GNSSs emerge from several countries around the world.
Teunissen cites new satellite positioning systems development across Europe, China, Russia, Japan, and India.
By 2016, more than 100 GNSS satellites will be in operation, with the result being a broader and more diverse system of satellites, he said.
The emergence of these new GNSSs, together with the linking of different systems has enormous potential for improving the accuracy, integrity, and efficiency of positioning worldwide.
