GSDM: Novel GNSS Spoofing Detection and Mitigation

This research project addresses one of the most critical challenges in modern aviation: GNSS spoofing attacks, which can compromise aircraft safety by broadcasting false satellite signals. In collaboration with CMC Electronics, Safran Trusted 4D, and Jaunt Air Mobility, the LASSENA laboratory at ÉTS will develop innovative technologies for the detection, mitigation, and resilience of next-generation GNSS receivers. These systems will leverage multi-constellation diversity (GPS, Galileo, BeiDou), the integration of inertial sensors (IMUs), and advanced artificial intelligence techniques to ensure robust, real-time protection against spoofing.

On the scientific front, the project will advance understanding of anomaly detection mechanisms, adaptive threat classification, and resilient navigation system architectures. It will also contribute to the creation of new validation and performance standards for spoofing-resilient GNSS systems, standards that currently do not exist in aviation.

A central objective of the project is the training of 68 highly qualified personnel (HQP), including master’s and PhD students, as well as postdoctoral researchers. These HQPs will benefit from interdisciplinary supervision and direct exposure to industrial R&D environments, strengthening their skills in GNSS, cybersecurity, and embedded systems.

For the industrial partners, the project will yield concrete technological outcomes:

• CMC will maintain and grow its international leadership in avionics-grade GNSS systems;
• Safran will develop new functionalities in its GNSS simulator platform;
• Jaunt will gain access to critical safety technologies for its next-generation electric aircraft.

Ultimately, the project will strengthen the technological sovereignty of Quebec and Canada in the strategic field of secure air navigation.
