Accurate Positioning, Navigation, and Timing (PNT) is necessary for the operation of many Critical Infrastructure (CI) sectors. Since PNT is an evolving landscape, and multi-PNT ecosystems are increasingly vulnerable to attack, building PNT dependencies into future technologies is progressively more important. As adverse impacts to PNT disruption become more widespread and longer lasting, precision timing becomes more important for continued resilience within CI systems such as the electric grid, communication networks, and financial institutions.

Through coordination with CI Owners and Operators (CI O&O), S&T aims to improve Direct Injection Test and Evaluation capabilities through the development of common representative configurations for Systems of Systems (SoS). The work will focus on providing several sectors-such as communications, the electrical subsector and emergency services-a better understanding of the impacts of potential disruption.
