Interference, jamming and spoofing detection.

Technologies

• GNSS interference monitoring Fixed sensors that detect and characterise GNSS interference near critical sites; detection and reporting only.
• Spoofing detection Signal-level checks, authentication and cross-checks with other sources that flag counterfeit GNSS signals.
• Jammer location to support enforcement Locating jamming sources and passing evidence to the regulator, which holds enforcement authority.
• Timing anomaly detection Watching time error and source agreement so a bad reference is rejected before it spreads.
• Interference-resistant antennas Multi-element and null-steering antennas that reduce the effect of interference on receivers.
• Aviation and maritime GNSS disruption awareness Sharing detected disruption with aviation and marine users through the proper authorities.
• Red line: no jamming or spoofing capability This work is limited to detection, location and resilience; no transmitter that denies or falsifies PNT is designed or deployed.
