DHS Builds Position, Navigation and Timing Framework

摘要

Over the next year, U.S. government officials intend to develop an initial conformance framework to ultimately improve resilience for systems that provide positioning, navigation and timing for a wide variety of users. That initial framework will focus on timing, and lessons learned will be used to develop more comprehensive versions. Accurate position, navigation and timing (PNT) is essential for the proper function of much of the nation's critical infrastructure. Traffic signal lights, aircraft, automatic teller machines and military operations all depend on it, mostly in the form of Global Positioning System (GPS) satellite signals. Precise timing is one aspect that is particularly important. Some critical infrastructure systems, including the electric grid, communication networks and financial institutions, require
