Spaced Based Infrared System (SBIRS) High
Abstract
The Space-Based Infrared Systems (SBIRS) primary mission is to provide initial warning of a ballistic missile attack on the US, its deployed forces, and its allies. SBIRS will incorporate new technologies to enhance detection and improve reporting of intercontinental ballistic missile launches, submarine launched ballistic missile launches, and tactical ballistic missile launches. SBIRS supports Missile Defense, Battlespace Awareness, and Technical Intelligence missions by providing reliable, accurate, and timely data to Unified Combatant Commanders, Joint Task Force (JTF) Commanders, the intelligence community, and other users. SBIRS provides increased detection and tracking performance in order to meet requirements in Air Force Space Command's Operational Requirements Document. The SBIRS system includes both space and ground elements. The space segment consists of Geosynchronous Earth Orbit (GEO) satellites, payloads hosted on satellites in Highly Elliptical Orbit (HEO), and Defense Support Program (DSP) satellites. The ground segment consists of both fixed and mobile data processing elements, communications infrastructure, and relay ground stations serving all SBIRS space elements. The HEO-1 and HEO-2 payloads are on-orbit and certified for Integrated Tactical Warning/Attack Assessment (ITW/AA) missile warning operations and technical intelligence operations. The GEO-1 satellite is on-orbit and is undergoing testing and calibration to prepare for operational acceptance. GEO-2 is scheduled for delivery in 3Q FY12 and launch in FY13. Ground segment development continues through the FYDP. Concept studies/activities may be implemented to investigate obsolescence issues, Overhead Persistent Infrared (OPIR) solutions to potential operational concerns, and future evolution paths of the ground and/or space segment. Space Modernization Initiative (SMI) efforts will include enhancing the current SBIRS to increase transmission security (TranSec), to manage obsolescence, and to mitigate risk. Evolved SBIRS Architecture activities will investigate affordable ways to modify the pointing control assembly, simplify existing payload and potentially accelerate calibration activities enabling an early operational acceptance of on-orbit staring capabilities. Data exploitation activities include OPIR data processing, data publication, algorithm development, network connectivity, data archiving and sensor performance assessments. The efforts will identify affordable, responsive, and resilient measures to get critical battlespace awareness information to the warfighter. They will also investigate substantial reductions in sensor-to-shooter processing and transmittal times so that tactical commanders can respond to enemy threats more quickly and accurately. Hosted payload technology testbed efforts will explore technology maturation, qualification of new components, and subsystem/component prototyping. These efforts will include demonstrations, architecture, system integration and testing, and data exploitation activities. The Department of Defense terminated the Third Generation Infrared Surveillance (3GIRS) program (PE 0604443F) beginning in FY11. 3GIRS included development efforts for the Commercially Hosted Infrared Payload (CHIRP) demonstration. FY11 and FY12 funds supporting the CHIRP demonstration for technology maturation of space and ground technologies were moved to the SBIRS RDT&E program element under a separate project number. CHIRP will perform risk reduction and evaluation of Wide-Field-of-View (WFOV) IR staring and data processing technology to potentially evolve future SBIRS staring sensors and processing algorithms. An on-orbit demonstration will quantify performance levels of a WFOV sensor in an operational environment. CHIRP sensor testing will also provide Focal Plane Array (FPA) performance/calibration characteristics, validate WFOV staring algorithm performance in an operational environment, and investigate compatibility with current Overhead Persistent Infrared (OPIR) ground systems for missile warning, missile defense, and other mission areas. This program is assigned to Budget Activity 5, System Development and Demonstration (SDD), because it funds the development and integration of mature systems, and the test, evaluation, and demonstration of those systems.
