Resilient PNT Reference Architecture Implementation Plan Fact Sheet

Positioning, Navigation, and Timing (PNT) services play a pivotal role in numerous critical applications across various sectors. Essential infrastructure, including communications networks, financial systems, emergency response, utilities, and transportation, heavily rely on PNT data to deliver services globally. Natural disasters, accidents, or attacks can disrupt PNT services, leading to adverse consequences for individuals, businesses, and nations alike. To counteract these threats, the Department of Homeland Security Science and Technology Directorate is researching ways to bolster PNT resilience, including safeguarding existing services and developing alternative PNT systems. The Resilient PNT (RPNT) Reference Implementation (RI) is designed to demonstrate the value of the RPNT Reference Architecture’s (RA) resilience concepts, aimed at motivating RPNT user equipment component manufacturers and integrators to incorporate these resilience concepts into their user equipment designs and to encourage operators to incorporate RPNT user equipment into critical infrastructure applications.
