-Description |
Overview (U):(U) NAVWAR is a joint service effort to protect U.S. and Allied forces from GPS disruption, and to prevent hostile forces from using GPS with minimal impact on the civil community outside the area of conflict. This effort is an outflow from a Defense Science Board (DSB) study (1995). Further guidance was provided in an 18 Mar 96 Joint Memorandum signed by USD(A&T) and the Vice Chairman Joint Chiefs of Staff (VCJCS), for the initiation of NAVWAR activities within the Department of Defense. This memorandum delineated organizational responsibilities and near-term efforts necessary to support a NAVWAR program. |
(U) The overall goal for the NAVWAR program is to prevent use of GPS by hostile forces on the battlefield while ensuring unimpeded use of GPS for U.S. and Allied forces. The NAVWAR program has two major elements: Protection and Prevention.
(U) SMC/CZ manages the protection activities. This effort is designed primarily to ensure GPS signals are received by warfighters in an electronically challenged environment. Additionally, the requirement to protect U.S. use of GPS is designed to address any attempt by hostile forces to deny U.S. and Allied use of this vital military utility. There is an on-going Advanced Concept Technology Demonstration (ACTD) program to enhance existing UE. The objective of the Engineering Manufacturing Development (EMD) phase is to acquire and demonstrate advanced GPS user equipment avionics with specific protection features. Contract award for the EMD phase is currently anticipated for Jan 99, with a period of performance concluding in FY 2000.
(U) Electronic Systems Command (ESC) is responsible for the prevention activities. However, overall responsibility remains with GPS JPO. ESC supports Analysis of Alternatives (AOA), Operational Requirements Document (ORD) and Concept of Operations (CONOPS) development, plans and acquires systems for/by the Air Force and coordinates other developments. The NAVWAR Prevention Program ensures that capability exists to deny the use of space-based navigation systems to the enemy within an Area of Responsibility (AOR) while minimizing signal fratricide and the effect on the civilian population outside the AOR. The program has subelements within the framework of the overall program. Each element focuses on separate yet complimentary operational objectives. In addition, SMC manages an on-going ACTD prevention program at SMC which has successfully demonstrated this prevention capability during FY 97.
(U) Throughout the execution of this program, the NET will incrementally assess technologies and their ability to effectively satisfy mission needs. Those technologies that are the most promising and proven will be incorporated into the overall NAVWAR architecture. The NAVWAR concept is for US and Allied to maintain navigation superiority on any future battlefield. The prevention hardware, software, and techniques developed may be capable of being employed many ways from a variety of platforms, in a multitude of operational environments. Additionally, advanced protection technologies may be incorporated into current DoD GPS receivers to improve their operational capabilities.
(U) Related Initiatives:
(U) The NAVWAR ACTD effort was designed NAVWAR to be the catalyst to a much larger effort for providing full operational capability. The ACTD is focused on demonstrating the technologies and the CONOPS by implementing electronic warfare (EW) countermeasures. The Navwar Protection Program is focused on developing promising technologies to enhance operational capability in both friendly and hostile EW environments. EW protection technology enhancements are being developed and implemented into a small number of current DoD GPS receivers, the Miniaturized Airborne GPS Receiver Upgrade (MAGRU), the handheld Precision Lightweight GPS Receiver Upgrade (PLGRU) and the Embedded GPS Inertial Navigation System Upgrade (EGIU) a modern navigation device combining a GPS receiver card with an inertial navigation system card.
(U) There will continue to be significant growth of new GPS applications which necessitates continued emphasis on the JPO's role as technology manager and consultant in order to accommodate new customers and products to satisfy new requirements and applications. In this role, the JPO will:
(U) coordinate closely with all GPS users to determine future UE requirements with sufficient planning to allow for timely acquisition,
(U) coordinate closely with GPS UE manufacturers and R&D laboratories to stay abreast of the latest technology developments that may have an application to future GPS UE requirements
(U) and support and participate in technology transfer to the private/commercial sector.
(U) The implementation of GPS is integral to all DoD operations. Improvements to the GPS program continue and are dependent on evolving CONOPS. Improvement to the receiver performance in electronically challenged environments is also a high priority.
(U) Programmed.
