Frequentis is responding to the urgency of protecting satellite navigation from interference to ensure safe aviation by presenting an innovative solution for automated live monitoring and detection of Global Navigation Satellite Systems (GNSS) spoofing and jamming by Frequentis’ partner company Dimetor, based in Austria.
Aviation safety relies heavily on GNSS, which are increasingly targeted by cyber-attacks. Because GNSS signals are unencrypted, they are vulnerable to jamming and spoofing- threats that can cause serious disruptions to air traffic. In early 2025, the International Civil Aviation Organisation (ICAO) and other global bodies urged states to better protect this critical radio-frequency band.
In response, Frequentis is presenting Dimetor’s patented NAVSentry at Airspace World. The software uses mobile network data to detect GNSS interference in real time, providing detailed alerts to air traffic systems to help ensure safer operations.
“With our mission to contribute to increased safety and performance in Air Traffic Management and Uncrewed Air Traffic Management, we bring an answer to the urgent challenge of GNSS interference to the international ATM community gathering in Lisbon. Our partner Dimetor provides an exceptional solution to answer this need,” says Frequentis air traffic management vice-president Reinhard Grimm.
NAVSentry supports a more proactive safety approach by continuously monitoring the airspace for signal interference. By providing earlier and broader awareness of spoofing and jamming threats, it complements Frequentis’ and Dimetor’s mission to deliver safer, more resilient airspace operations.
“We are proud to partner with Frequentis to introduce NAVSentry to the ATM community. The solution offers unrivalled GNSS interference protection and enables a new safety concept by providing wider, real-time insight into spoofing and jamming through mobile network data. This significantly enhances aviation safety,” says Dimetor CEO Thomas Neubauer.
Frequentis and Dimetor plan to further integrate their capabilities to enrich the services Frequentis delivers to air navigation service providers worldwide.
