Interfering with GNSS signals Building PNT Resilience with Silicon Timing

In the modern era, cyber-attacks and other electronic sabotage against critical services, networks and utilities are becoming more powerful as societies depend increasingly on connected systems and infrastructure. Among critical infrastructure targets, interfering with GNSS signals is an increasingly common technique.

Positioning, Navigation, and Timing (PNT) information is critically important for a wide variety of civil and commercial activities including air and sea transport, road haulage, and private motoring, as well as general logistics.  The UK government estimates that a 24-hour PNT outage could cost the economy £1.4 billion.
