Radionavigation Systems Planning
Federal Radionavigation Plan
The Federal Radionavigation Plan (FRP) is the official source of positioning, navigation, and timing (PNT) policy and planning for the Federal Government. It is required by the National Defense Authorization Act for Fiscal Year 1998, as published under Title 10 United States Code, Section 2281, paragraph (c) (10 USC 2281(c)). The FRP is prepared jointly by the Departments of Defense (DoD), Homeland Security (DHS), and Transportation (DOT), with the assistance of other government agencies. The FRP reflects the policy and planning for present and future federally provided PNT systems, covering common-use PNT systems (i.e., systems used by both civil and military sectors). Systems used exclusively by the military are covered in the Chairman, Joint Chiefs of Staff Instruction 6130.01D, the DoD Master Positioning, Navigation, and Timing Plan (MPNTP).
The FRP contains chapters covering Roles and Responsibilities, Policy, PNT User Requirements, Operating Plans, and the National PNT Architecture, as well as appendices covering System Parameters and Descriptions, PNT Information Services, and Geodetic Reference Systems and Datums. It is updated biennially, allowing more efficient and responsive updates of policy and planning information. The 2010 edition is the most recent version of the FRP.
Radionavigation Systems: A Capabilities Investment Strategy (2004)
The continued operation, maintenance, and upgrade of our Federal navigation infrastructure must ensure a robust mix of systems based on analyses of the capabilities, requirements, benefits, costs, and risks associated with the various options. Currently, a dependable but aging array of ground-based systems and technologies exists in parallel with state of the art satellite navigation systems. As worldwide use of GPS and its augmentations has increased, so too has the need to protect our transportation infrastructure against the interruption or loss of signals from GPS.
The Radionavigation Capabilities Assessment Task Force was established to develop a multi-modal capabilities assessment and recommend to the Secretary of Transportation a radionavigation investment strategy that will meet our national transportation requirements. That assessment and recommendation are set forth in the 2004 Report.
