Joint Precision Approach and Landing System

Abstract

Joint Precision Approach and Landing System (JPALS) is a joint effort among the USAF, Navy/USMC, and Army. The Air Force is responsible for developing the common system architecture for Land-Based increments. The Joint Requirements Oversight Council (JROC) approved the Capability Description Document (CDD) for the JPALS Family of Systems and the Annex for Increment 1 (Sea-Based) in March 2007 and transferred lead service responsibility to the Navy. JPALS is the future precision approach and landing system for the Department of Defense (DoD). It will provide a joint operational capability for U.S. forces to perform assigned missions within and from fixed-base, tactical, shipboard, and special operations environments under a wide range of meteorological conditions. Land-Based JPALS will provide DoD civil interoperability with the Federal Aviation Administration's (FAA) Local Area Augmentation System (LAAS). JPALS is participating in the development, testing, and implementation of international standards (to include North American Treaty Organization (NATO) standardization agreements) to ensure joint, allied, and coalition interoperability. When complete, this effort will replace aging shipboard and ground-based precision approach and landing systems (Instrument Landing System, Precision Approach Radar, Microwave Landing System, and Automated Carrier Landing Systems). JPALS will facilitate DoD missions and training by enabling U.S. forces to land on any JPALS equipped airfield worldwide (land and sea) under peacetime and hostile conditions. JPALS will close capability gaps identified in the 2005 Precision Approach and Landing Capability Initial Capabilities Document (ICD). These gaps are interoperability for naval aircraft landing at shore-based airfields operated by other services, interoperability for Navy/Marine Corps and Army aircraft landing at civil airports, and for the Civil Reserve Air Fleet (CRAF) landing at DoD airfields. The 2005 JPALS Precision Approach and Landing ICD identified a family of systems (FoS) based on Global Positioning System (GPS) technology solutions for fixed base, tactical, and sea-based environments. JPALS must provide needed guidance quality in the presence of GPS jamming. The JPALS architecture must be developed to integrate and synchronize with related Communication, Navigation, and Surveillance/Air Traffic Management (CNS/ATM), GPS modernization initiatives, and net-centric operations. Finally, because a cornerstone of the JPALS implementation strategy is worldwide military and civil interoperability, JPALS must harmonize with US and international civil Global Navigation Satellite Systems. FY11 efforts continue risk reduction activities related to incorporating JPALS capability in existing avionics and the evolutionary acquisition strategy in preparation for Milestone B, including completion of the technology readiness assessment with OSD participation, and a greater emphasis on aircraft integration activities. The degree of test activity will decline, with ramp-up scheduled in advance of the Engineering, and Manufacturing and Development (EMD) contract award in FY13. This program is in budget activity 4, Advanced Component Development and Prototypes Research Category 6.4B, because supportability and manufacturing process design considerations must be identified and integration into the precision landing system architecture. .
