New Delhi: RMIT University is collaborating with Indian microchip manufacturers and Australian air traffic management company Skykraft to develop an alternative to the US-owned GPS technology. The initiative is backed by a $3.7 million grant from the Australian Government and aims to create independent positioning, navigation, and timing (PNT) systems for critical sectors.
Professor Suelynn Choy from RMIT’s School of Science highlighted the importance of diversifying navigation systems. “The global reliance on GPS makes entire regions vulnerable if the system fails,” she said. Countries like Australia and India, with vast landmasses and industries dependent on accurate PNT data, require adaptable technologies to address unique challenges.
Focus on Low Earth Orbit Satellites and Microcombs
The project focuses on low earth orbit (LEO) satellites, which provide stronger signals and are less prone to interference. These satellites can be deployed where coverage is needed most, offering a reliable backup to global navigation satellite systems.
Central to the effort is RMIT’s groundbreaking microcombs technology. These photonic microchips, which leverage light-based systems, are being developed for PNT applications. Distinguished Professor Arnan Mitchell, Director of the Australian Research Council Centre of Excellence in Optical Microcombs, stated that the technology’s adaptability and portability could revolutionize satellite networks.
Strengthening India-Australia Ties
This partnership also aims to enhance collaboration between Australia and India, establishing a supply chain for advanced microchip production. “This initiative provides an opportunity to find innovative solutions for global navigation challenges while strengthening ties between the two nations,” said Professor Mitchell.
The project reflects growing efforts by nations to reduce reliance on external providers like the US and Europe, ensuring sovereign control over critical infrastructure for industries and national security.
