Flight Ready: Joint Precision Approach and Landing System (video)

Engineers at Naval Air Station Patuxent River, Md., discuss the successful evolution of the Joint Precision Approach and Landing System (JPALS). Learn more about this innovative technology from inception to the first ship board landing aboard the aircraft carrier USS Theodore Roosevelt (CVN-71) off the coast of Norfolk, VA.

Mission

JPALS is an all-weather landing system based on differential GPS for land-based and sea-based aircraft.


Description

JPALS works with the GPS satellite navigation system to provide accurate, reliable and high-integrity guidance for fixed- and rotary-wing aircraft. The system features anti-jam protection to ensure mission continuity in hostile environments. JPALS is a differential GPS that will provide an adverse weather precision approach and landing capability.
