Positioning, Navigation, and Timing (PNT) services are used in several sectors of the nation’s critical infrastructure. Essential services such as 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 individual, businesses and nations alike. To counteract these threats, the Department of Homeland Security (DHS) Science and Technology Directorate (S&T) continues to research ways to strengthen PNT resilience, including safeguarding existing services and developing alternative PNT systems.
In an effort to ensure robust resilient PNT, the Test Vector Suite will identify and define appropriate test scenarios that support standards conformity assessments and GNSS test vectors based on these test scenarios; and provide these test vectors in a compact representation that can be hosted by existing share sites, forming a proof-of-concept for the distribution methodology.
