Positioning, Navigation and Timing (PNT) & Spectrum Management
Navigating from Point A to Point B safely and efficiently is critical to all modes of transportation making Positioning Navigation and Timing (PNT) capabilities and technologies a vital part of the global infrastructure. The Department of Transportation is the lead for civil PNT requirements and represents the civil Departments and Agencies in the development, acquisition, management, and operations of the Global Positioning System (GPS).
DOT’s Office of Positioning, Navigation, and Timing (PNT) and Spectrum Management coordinates the development of Departmental positions on PNT and Spectrum Policy to ensure safety, mobility, and efficiency of the transportation network. The Office is a program of the Office of the Assistant Secretary for Research and Technology.
While we lead the Department’s broad responsibilities on PNT matters, with a special focus on GPS interference, developing GPS civil requirements and coordinating civil PNT funding, our office plays an additional key role: we provide civil PNT systems and policy analysis and coordination for all Federal civil Departments and Agencies. We also represent those agencies in the development, acquisition, management, and operations of GPS, including requirements development.
