hensec introduces AGNOST-A, an early-warning system that alerts pilots to GNSS jamming and spoofing threats at destination airports, enhancing operational awareness and safety.
Early-warning solution targets growing risk of navigation signal interference
A new system designed to detect and warn pilots of satellite navigation interference has been introduced by hensec, addressing the increasing operational risk posed by GNSS jamming and spoofing in civil aviation.
The system, known as AGNOST-A, was presented at AERO Friedrichshafen 2026 and is intended to provide early warning of signal disruption in the vicinity of destination airports.
EARLY WARNING BEFORE ARRIVAL
GNSS interference, including both jamming and spoofing, has become an increasingly reported issue, with pilots encountering unreliable GPS-based navigation systems during flight.
AGNOST-A is designed to detect and analyse such disruptions in real time. When interference exceeds a defined threshold, the system automatically generates a Notice to Airmen (NOTAM), which is transmitted via a dedicated data link channel (UAT978) across the affected area.
Aircraft equipped with compatible receivers can display these warnings directly in the cockpit, allowing flight crews to assess navigation reliability well before arrival and make informed operational decisions.
INFRASTRUCTURE-BASED DEPLOYMENT
The system is housed in a weatherproof control cabinet designed for installation at airports and airfields, enabling localised monitoring of GNSS signal integrity. According to the developer, the solution represents a first-of-its-kind implementation in this operational context.
ADDRESSING A GROWING THREAT ENVIRONMENT
The rise in GNSS interference reflects a broader shift in aviation risk, where digital and electronic vulnerabilities are increasingly intersecting with operational safety. Systems such as AGNOST-A aim to provide an additional layer of situational awareness, particularly in environments where reliance on satellite navigation is critical.
hensec focuses on integrated security approaches combining physical and cyber domains, with applications spanning critical infrastructure protection, counter-surveillance, and aviation-related security systems.
