Resilient PNT Standard IEEE Conformity Assessment Program Fact Sheet

Positioning, Navigation, and Timing (PNT) services play a pivotal role in the nation’s Critical Infrastructure (CI). Essential services such as communications networks, financial systems, emergency response, utilities, and transportation rely heavily on PNT data to operate. Natural disasters, accidents, or deliberate actions pose threats that can disrupt PNT services, leading to adverse consequences for individuals, businesses, and the nation as a whole. To counter these threats, the Department of Homeland Security Science and Technology Directorate is researching new ways to strengthen PNT resilience, including safeguarding existing services and developing alternative PNT systems. The IEEE Conformity Assessment Program (ICAP) provides the technical means to verify standard compliance and credibility for CI end users.
