GNSS RFI
Monitoring
SecureTrack provides integrated airspace and ground GNSS RFI monitoring that gives operators situational awareness for navigation reliability across the airspace.
Airspace GNSS RFI monitoring uses ADS-B position reports and multilateration-derived aircraft positions to identify aircraft affected by corrupted GNSS signals, while ground-based monitoring detects jamming and spoofing at airports and critical infrastructure. Real-time alerts notify operators when aircraft are affected by jamming or spoofing, enabling rapid response and improved situational awareness.
Ground GNSS signal measurements cover multiple constellations (GPS, GLONASS, Galileo, Beidu) and multiple frequencies (e.g., the GPS L1, L2, and L5 frequency bands). Our control-room interface provides real-time situational awareness of GNSS interference conditions across the monitored environment.
SecureTrack provides ICAO Annex 10 Vol. 1-compliant GNSS performance recording and historical data analysis across air and ground monitoring environments to support investigation, reporting, and regulatory requirements.
