Protecting GNSS Systems Against Interference, Jamming and Spoofing

As global reliance on GNSS for positioning, navigation, and timing continues to grow, so does the risk of disruption. Both deliberate and accidental GNSS interference — including jamming and spoofing — are increasing in frequency and sophistication.

For critical infrastructure, communications networks, timing systems, and autonomous operations, even brief signal disruption can lead to safety risks, operational downtime, financial loss, and reduced trust in system performance.

GNSS jamming detection and monitoring are no longer optional — they are essential for maintaining resilience, continuity, and security in today’s connected world.

Our advanced range of GNSS jamming, spoofing, and interference detection sensors and probes is designed to help organisations identify threats early, analyse signal quality in real time, and respond with confidence.

By continuously monitoring the GNSS spectrum, our solutions detect and classify anomalies, enabling users to understand the source, severity, and impact of interference events.

Why GNSS Interference Monitoring Matters

Industries that depend on precise positioning and timing — including transport, defence, telecommunications, energy, infrastructure, and autonomous systems — require uninterrupted GNSS availability.

Without effective monitoring, interference events can go unnoticed until they cause mission failure, navigation errors, or system outages.
