Several national critical functions and all 16 critical infrastructure sectors rely either directly or indirectly on functional and consistent position, navigation, and timing (PNT) signals. As such, fragility of weak and easily imitated global positioning system (GPS) signals could lead to catastrophic impacts on dependent and interdependent critical infrastructure systems. Designating PNT-signal-emanating assets as a standalone national critical function would bring resources, awareness, research, additional risk mitigation measures, and new solutions to help keep consistent and resilient PNT signals operational if threatened by natural and human-caused threats.
