GNSS is an amazing system and has revolutionized positioning, navigation, and timing (PNT) over the last twenty years, but the conclusions are clear: GNSS vulnerability is real, the risk is increasing, and we need urgently to improve interference detection and mitigation.
Many of the GNSS-related benefits that we enjoy today are the result of integrated systems, automation, and new, high-performance concepts of operation with fewer and less-skilled people. Reversion to older concepts of operation is not an option in many cases and so we must build resilience into our systems.
