Satellite Navigation - GPS - Policy - NPEF

GPS Policy - National PNT Engineering Forum


The National PNT Engineering Forum (NPEF) is a multi-agency technical forum that supports policy and managerial decisions regarding the evolution of GPS. As the capabilities of Global Positioning System (GPS) continue evolve, the technical needs of a wide range of existing and future civil applications need to be considered. The NPEF has been established to work a variety of issues including L5 compatibility, GPS spectrum, GPS timing, and public outreach from a systems engineering perspective.

The NPEF was originally established under a different name - the GPS System Engineering Forum (GSEF). In 2002, the GSEF was established to provide a forum for the discussion of systems engineering issues and technology development opportunities relative to GPS and GPS augmentations that influence or are influenced by managerial or policy decisions. In 2004, this group was formally recognized and established as a permanent working group under the auspices of the National Space-Based Position, Navigation, and Timing (PNT) Executive Committee and Coordination Office. Early in 2007, the GSEF name was changed to more accurately reflect this association to the PNT.

The NPEF is co-chaired by the Department of Defense (Air Force) and the Department of Transportation (Federal Aviation Administration) and comprised of representatives from various government agencies. Core membership includes engineering representatives from:

  • FAA Aircraft Certification Office
  • U.S. Coast Guard Maritime Differential GPS Program
  • National Oceanic and Atmospheric Administration (NOAA) National Geodetic Survey
  • National Aeronautics and Space Administration (NASA)
  • U.S. Naval Observatory
  • U.S. Geological Survey

Participation in the NPEF from industry and/or public groups is welcome. Those interested in participating in future meetings may contact the applicable co-chair for information. Those interested from the civil community should contact FAA's co-chair Deane Bunce. The point-of-contact for the military community is the co-chair from the Air Force, Mr. James Horejsi.
