Revealing the Hidden Risks: GNSS Spoofing in Aviation

How CTU used Spirent’s simulation tools to expose the aviation sector’s vulnerabilities to GNSS spoofing, revealing real-world risks and helping shape stronger defences against interference.

Modern aviation depends on GPS and other GNSS signals for navigation, surveillance, and time synchronization. But these signals are inherently weak—and increasingly under threat from interference and spoofing attacks. Spoofing, in particular, can mislead GNSS receivers into reporting false positions, disrupting aircraft operations in subtle but dangerous ways.

Despite its growing prevalence, the aviation industry’s understanding of spoofing’s real-world impact has remained limited—until now.
