Published purpose

This project aims to strengthen the resilience of satellite-based positioning, navigation and timing services by advancing low-Earth orbit positioning, navigation and timing (LEO-PNT) technology as a complement to existing global navigation satellite systems (GPS and more generally GNSS), which remain vulnerable to interference and disruption. The expected results include characterizing navigation signals and ranging performance from new LEO-PNT satellites, new timing solutions, pioneering research in satellite-based indoor positioning, and enhanced ground-based GNSS + LEO-PNT solutions. The project will also train students in specialized space technology skills and contribute to increased dual-use PNT technology resilience for Canadians, supporting applications such as autonomous vehicles, smartphone positioning, urban and indoor navigation, and critical infrastructure timing for utilities and financial systems.
