RMIT University Partners With Microchip Manufacturers In India For Alternative To GPS Technology
Under the Australia and India partnership, a satellite navigation system is being scaled up for low Earth orbit applications. The system is incorporating light-based microchip technology.
Study in Australia: RMIT University is entering a partnership to explore an alternative to the US-owned Global Positioning System (GPS) technology. For this RMIT University has been given a $3.7 million Australian Government grant and it is partnering with microchip manufacturers in India and Australian air traffic management company Skykraft.
Commenting on this, Professor Suelynn Choy, Professor of Satellite Navigation at RMIT’s School of Science said, "Developing alternative, sovereign navigation systems ensured that countries such as Australia and India had back-up systems and were not solely reliant on external providers in the United States and Europe for critical PNT infrastructure. The global reliance on GPS makes entire regions vulnerable to losing positioning, navigation and timing data if the system fails. Australia and India have some very specific challenges and opportunities – particularly our large land mass, vast borders and primary industries relying on positioning, navigation and timing data – GPS may not be the right technology for all of these needs. These satellites are easier and less expensive to launch, and they allow for more flexibility by being deployed where coverage is needed most, providing a backup to other global navigation satellite systems.”
“Low earth orbit PNT technology could deliver stronger signals that were less vulnerable to interference,” she said.
RMIT University's Alternative To GPS System: More Details
RMIT's system is called microcombs and the RMIT's researchers are leading in this technology in the world. This technology is based on photonic microchips which are easily adaptable to any application using light including positioning, navigation and timing (PNT) capabilities.
The new partnerships will help in advancing the development of these chips for PNT applications and it will also establish a supply chain between the nations.
Distinguished Professor Arnan Mitchell, Director of the Australian Research Council Centre of Excellence in Optical Microcombs for Breakthrough Science (COMBS) at RMIT, said, “This portability opens up opportunities for more accessible and deployable satellite networks. This project presents an exciting opportunity for forming closer ties between Australia and India, where we collaborate to develop our microcombs technology and find innovative solutions for global positioning, navigation and timing challenges.”
