Joint Tactical Ground System

Abstract

This system is an integral part of the overall Air and Missile Defense (AMD) architecture and will provide for an incrementally fielded Integrated Air and Missile Defense Fire Control System/capability for the composite Army Air and Missile Defense Brigades. This program element supports development of critical improvements and insertion of technology upgrades to the Joint Tactical Ground Station (JTAGS) and the research and development of the JTAGS Pre-Planned Product Improvement (P3I). JTAGS is presently a transportable information processing system that receives and processes in-theater, direct down-linked data from Defense Support Program (DSP) satellites. JTAGS disseminates warning, alerting, and cueing information on Ballistic Missiles and other tactical events of interest throughout the theater using existing communication networks. This program is designated as a DoD Space program. JTAGS provides critical support by providing Combatant Commanders near real-time warning of theater ballistic missiles and other battle space characterization information in their Areas of Responsibility (AOR). The four OCONUS deployed JTAGS units constitute the DoD's only in-theater system providing space-based warning. JTAGS is designated as the in-theater element of the United States Strategic Command's Theater Event System. JTAGS supports all Theater Missile Defense pillars and by being located in-theater, provides the shortest sensor to shooter connectivity. The objectives of the improvements are to upgrade JTAGS to a new configuration for operation with the next generation of Space Based Infrared System (SBIRS) satellites, and to improve warning accuracy and timeliness. These improvements will be accomplished in a two-Block P3I Program development effort. Block 1 activities include Information Assurance (IA) upgrades: Highly Elliptical Orbit (HEO) Automation Track Transfer (ATT) Integration bridging Initial Geosynchronous Capability (IGC); new commercial antennas; Source on Source (SoS) Upgrade; and SIPRNET capability. Utilizing FY12 and out years funding, Block 2 upgrades will be executed in two phases. Phase 1 upgrade includes desheltering five systems and the reintegration of the various hardware/software/communication systems into operation centers and Geosynchronous (GEO) scanner capability (FY 13-14).
