A government-industry team accomplished the first precision approach by a civil aircraft using a military Global Positioning System (GPS) landing system at Holloman AFB, N.M.

Raytheon designed and developed the differential GPS landing system under an Air Force contract for the Joint Precision Approach and Landing System (JPALS) program. More than 200 precision approaches with a military test aircraft have been accomplished to date.

  • JPALS is an all-weather, all-mission, all-user landing system based on local area differential Global Positioning System (GPS).
  • JPALS works with GPS to provide accurate, reliable, landing guidance for fixed and rotary wing aircraft during all weather conditions. It features a high GPS anti-jam protection to assure mission continuity in a hostile environment.
  • JPALS equipment supports fixed-base, tactical, and shipboard applications. It is compatible with civil and military GPS signals.

The JPALS system is being developed to meet the Defense Department's need for an anti-jam, secure, all weather Category I/II/III aircraft landing system that will be fully interoperable with planned civil systems utilizing the same technology.
