Oscilloquartz, a leader in precision timing solutions, highlights a growing threat to global aviation: cyberattacks targeting the Global Navigation Satellite System (GNSS). Learn more > >
A recent European Union Aviation Safety Agency (EASA) bulletin warns that incidents of GNSS jamming and spoofing have surged, affecting not only aircraft navigation but also critical ground-based aviation infrastructure.
While many associate GNSS attacks with in-flight navigation errors, the broader impact lies in timing disruption. Modern aviation relies on precise synchronization for air traffic control, surveillance networks, and airport operations. Even brief timing interruptions can cascade across the system, compromising safety, efficiency, and operational costs.
GNSS attacks generally take two forms: jamming, which blocks signals outright, and spoofing, which injects false signals to mislead receivers. Both can cause false terrain alerts, misaligned aircraft positions, and disrupted communications.
Resilient timing solutions, such as those offered by Oscilloquartz, provide multi-layer protection. Advanced synchronization platforms enable real-time interference detection, multi-source backups, and fault-tolerant monitoring to ensure continuous operations. By strengthening both airborne and ground-based systems, the aviation industry can maintain safe, reliable, and efficient air transport despite rising GNSS threats.
