In an era where aviation relies heavily on satellite navigation, Frequentis and Dimetor have joined forces to introduce NAVSentry, a groundbreaking solution designed to protect Global Navigation Satellite Systems (GNSS) from interference.
With the increasing risks of GNSS jamming and spoofing, NAVSentry provides real-time monitoring and early detection of disruptions, ensuring safer skies for pilots and air traffic controllers. By leveraging advanced mobile network data, this innovative technology enhances situational awareness and strengthens aviation security.
Frequentis and Dimetor’s partnership marks a significant step forward in air traffic management (ATM), reinforcing the resilience of satellite navigation systems against emerging threats.
Discover how NAVSentry is shaping the future of aviation safety.
Aviation Safety Faces a New Threat — But a Solution Is Here
You may not see it, but every modern flight you take relies on satellite signals to navigate safely through the skies. These signals, known as GNSS (Global Navigation Satellite Systems), are essential for everything from takeoff to landing. But what happens when these signals are disrupted — or worse, manipulated?
This is the growing concern aviation experts are facing today. And in response, two key players, Frequentis and Dimetor, have partnered to deliver a vital solution: NAVSentry. Revealed at Airspace World 2025, this innovative technology aims to detect and alert for GNSS interference — keeping flights safer and air traffic operations more resilient.
Let’s explore how this new system works, why it matters, and what it means for the future of air travel.
The Invisible Risk in the Skies
GNSS is the silent hero of aviation. It helps aircraft determine their position, speed, and route with pinpoint accuracy. However, there’s a catch — GNSS signals are unencrypted and therefore vulnerable.
This makes them a target for two types of interference:
- Jamming, which blocks the signal entirely.
- Spoofing, which mimics legitimate signals and misleads aircraft systems.
Both threats can endanger flight safety by confusing pilots, delaying air traffic, or even misguiding planes. Recent global warnings from the International Civil Aviation Organisation (ICAO) have pushed the aviation community to act fast.
A Game-Changer in Interference Detection
That’s where NAVSentry enters the picture.
Developed by Dimetor and introduced through their collaboration with Frequentis, NAVSentry doesn’t rely on satellite systems to detect GNSS disruptions. Instead, it uses mobile network data to detect unusual signal behavior — identifying jamming and spoofing events in real time.
This approach brings a fresh perspective to aviation safety. Since mobile networks are everywhere and already cover most of our airspace, they become an unexpected but powerful tool in defending the skies.
Early Alerts Make All the Difference
NAVSentry isn’t just about detection. It’s about timely action.
When a spoofing or jamming incident is identified, the system sends live alerts to air traffic controllers and, where applicable, to pilots. This early warning gives teams the chance to adjust routes, avoid affected areas, or take other safety measures before the situation escalates.
For flights already airborne, every second counts. For flights preparing for takeoff, knowing the status of GNSS signals ahead of time is crucial.
By providing situational awareness early on, NAVSentry strengthens the foundation of proactive aviation safety.
Reinventing Safety Culture in Aviation
Frequentis is known for its commitment to innovation in Air Traffic Management (ATM) and Uncrewed Traffic Management (UTM). According to Reinhard Grimm, Vice President ATM at Frequentis, the partnership with Dimetor reflects a shared vision to not just react to threats — but to anticipate them.
“By bringing NAVSentry to the international ATM community, we offer an answer to the growing concern around GNSS interference,” he stated at the launch. “It’s about delivering safety — before disruption turns into danger.”
NAVSentry helps air navigation service providers (ANSPs) transition from passive to active monitoring of interference events, changing the way aviation deals with cyber-related risks.
A United Vision for Safer Skies
Thomas Neubauer, CEO of Dimetor, echoed this sentiment, highlighting the broader impact of their technology.
“We are proud to partner with Frequentis to offer NAVSentry as a key part of a new aviation safety concept,” he explained. “By leveraging real-time data and delivering actionable insights, we’re not just protecting navigation — we’re redefining what’s possible for secure airspace operations.”
The partnership is not just a one-off product launch. Both companies have shared plans to further integrate their technologies, expanding the range of services Frequentis can offer to air traffic agencies around the world.
Expanding Safety on a Global Scale
With airspace becoming more crowded and threats more sophisticated, solutions like NAVSentry are not just beneficial — they’re essential.
The move to secure satellite navigation is gaining global momentum, and Frequentis and Dimetor are positioning themselves at the forefront of that effort. Their focus is clear: equip aviation professionals with better tools, faster data, and greater awareness.
The road ahead includes continued development, broader system integration, and potential regulatory collaboration to ensure widespread adoption of GNSS interference detection.
Conclusion: Securing the Future of Flight
Staying Ahead of the Signal Threat
You may not hear about GNSS interference every day — but rest assured, it’s a concern top aviation authorities are taking seriously. As aircraft increasingly depend on satellite-based navigation, protecting those signals becomes a matter of life and safety.
Through the launch of NAVSentry, Frequentis and Dimetor are offering not just a product, but a vision for the future: one where air traffic is safeguarded against invisible threats, and where technology works ahead of the problem, not behind it.
For passengers, pilots, and air traffic managers alike, this marks a critical step toward more secure skies.
And as this innovation spreads, you can expect your next flight to benefit — not just from good weather or a skilled crew, but from technology quietly ensuring that every signal guiding you through the sky is trustworthy.
