Positioning, Navigation, and Timing (PNT) Service for National Critical Infrastructure Resiliency

This RFI provides an outline for the potential use by the Federal Government of one or more Positioning, Navigation, and Timing (PNT) technologies to back up signals from the Global Positioning System (GPS) and to ensure resiliency of PNT for U.S. Critical Infrastructure (CI) operations. As a co-chair and member of the National Executive Committee for Space-based PNT, and a provider and user of U.S. critical infrastructure services, the Department of Transportation is investigating opportunities by which the Federal Government may make use of service(s) which can provide the necessary backup capability or capabilities to ensure PNT continuity for U.S. CI in the event of a temporary disruption in GPS availability. Further, as the lead civil agency for PNT in the Federal Government, the Department of Transportation is interested in leveraging PNT service technology initiatives under consideration or currently undertaken by industry. The Federal Government is presently documenting civil requirements for PNT capabilities to serve as the basis for potential future acquisition activity. The initial objective is to support sustainment of domestic CI timing continuity with the capability to extend service(s) in the future to provide positioning/navigation continuity as well.
