On 12 February 2026, GMV and ENAIRE presented the results of ESA NAVISP EL2‑170, “STAGER – Sophisticated GNSS Threats Protection.”

The project developed a cost‑effective, COTS‑based GNSS RFI monitoring solution designed for dense deployment around critical infrastructure, combining the SILENT sensing nodes and the VAULT server‑side analysis platform. The system integrates multi‑layered detection, AI‑based jamming/spoofing classification, and geolocation capabilities using angle‑of‑arrival and power‑difference‑of‑arrival methods.

Results:

• AoA accuracy: <5° azimuth, <17° elevation.
• Geolocation accuracy: 0.5 km best, 11.81 km worst, 3.5 km mean.
• Spoofing detection correctness: PRNs 13/14/22 detected; PRNs 30/17 false positives
• AI performance: SVM cleanly separates jammed vs non‑jammed; VAE MSE threshold correctly flags spoofing
• False‑alarm / miss‑detection metrics: evaluated using confusion matrices in lab tests.
• Operational validation: real‑time system performance demonstrated at Jammertest 2025 (good azimuth, weaker elevation, improved localization with AoA+PDOA).
• Service‑impact assessment: afflicted airspace/volume computed using DEM + ITWOM 3.0.
• System maturity: TRL 7 achieved.

This project was co‑funded by NAVISP Element 2, boosting the competitiveness of European and Canadian resilient PNT solutions.
