PNT is primarily provided through the Global Positioning System (GPS) and other Global Navigation Satellite Systems (GNSS). PNT is not just used for navigation, though. It also provides precision timing information that enables critical functions within telecommunication networks and the power grid. However, these PNT services are susceptible to interference such as GPS jamming and spoofing, which pose a risk to critical infrastructure. What was once an emerging risk is quickly becoming a pressing issue, with industry reporting a growing trend in the past two years of prominent PNT disruption events around the world. As the technological barriers to conducting these activities continue to fall, it becomes even more important to ensure our critical infrastructure is resilient to PNT disruptions.
