Enhanced Long-Range Navigation (eLORAN)

MOA between DOD and DOT for Civil use of GPS

This Memorandum of Agreement (MOA) establishes policies and procedures to ensure an effective working relationship between the Department of Defense (DOD) and the Department of Transportation (DOT) regarding civil use of GPS.

September 2023, DOT Complementary PNT Action Plan

GPS Backup and Complementary PNT

DOT is working in conjunction with various Federal and civilian partners to develop and test critical backup GPS capability and complementary PNT services, ensuring a more robust and resilient national PNT architecture.

Executive Order (E.O.) establishing the first comprehensive national policy promoting the responsible use of PNT services by the Federal Government.

GPS Backup Demonstration: National Defense Authorization Act 2018, Section 1606

The Government, through a competitive acquisition process, has selected 11 candidate technologies to demonstrate Position and Timing capabilities in the absence of GPS over two demonstration sites.

Overview:

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.

The Civil GPS Service Interface Committee (CGSIC) is the recognized worldwide forum for effective interaction between all civil GPS users and the U.S. GPS authorities. DOT chairs the CGSIC and the USCG Navigation Center (NAVCEN) serves as the Deputy Chair and Executive Secretariat. The full Civil GPS Service Interface Committee convened in Baltimore, Maryland, U.S.A. in person and virtually, on September 16-17, 2024, in conjunction with the ION GNSS+ 2024 conference.
