On October 9, 2025, Sagax Communications & Pro Environ presented the results of the NAVISP EL2-109 activity “Cybersecure GNSS for Autonomous Mobility (CECIL)”.

The project addressed the growing threat of GNSS spoofing by developing a novel mitigation technique based on a multi-antenna sensor system. The CECIL prototype detects spoofed signals by comparing the reported satellite azimuth with the measured signal direction, flagging inconsistencies in real time.

The system was designed, manufactured, and validated through both laboratory and extensive field testing, including dynamic tests in open, suburban, and urban environments. Key results include:

• Reliable spoofing detection within 5 seconds at distances up to 250–300 meters
• High detection rates (>95%) with low false alarm rates (<5%) in open environments
• Robust performance at vehicle speeds up to 110 km/h
• Demonstrated effectiveness against low-cost spoofers like HackRF One

The project was co-funded by NAVISP Element 2, which supports the competitiveness of PNT technologies in partnership with industry. The slides of the final presentation can be found here.
