TRW/Raytheon SBIRS Low TeamCompletes Systems Requirements Review
(Source : TRW, Inc. ; issued Nov. 1, 2000)


REDONDO BEACH, Calif.---The TRW/Raytheon team reached a major milestone in the Space Based Infrared System (SBIRS) Low program with the recent completion of the Systems Requirements Review (SRR), the third in a series of three requirements reviews. SBIRS Low is the low-Earth orbiting component of the nation's next-generation missile early warning system.

The reviews represent significant accomplishments in the team's 38-month Program Definition and Risk Reduction (PDRR) contract, during which the team is defining requirements and completing designs for an operational system. As an essential part of the PDRR effort, the team is also conducting a series of high-value demonstrations designed to reduce program risks in key areas such as producibility, discrimination, and software development and integration.

"We have developed an affordable, flexible architecture to meet evolving threats, drawing on the extensive domain knowledge and truly innovative thinking of our world-class team,'' said Pat Caruana, vice president and program manager, SBIRS Low. "We have balanced cost, performance and risk to produce a best-value architecture for the government. With a successful SRR and solid architecture, we're running full steam into the design phase of the program.''

SBIRS Low will consist of a constellation of satellites equipped with infrared sensors capable of observing ballistic missiles in all phases of flight. SBIRS Low's unique capability to track a missile in midcourse flight enables more accurate and earlier discrimination of harmful re-entry vehicles from decoys, ultimately enhancing national and tactical missile defense assets. SBIRS Low also provides instantaneous global coverage for other critical missions including missile warning, battlespace characterization and technical intelligence.

As part of the SBIRS Systems of Systems (SoS), data gathered by SBIRS Low satellites will be integrated with the consolidated SBIRS ground station and Theater and National Missile Defense surveillance and weapons systems. The SoS includes satellites in geosynchronous orbits, sensors hosted on satellites in highly elliptical orbit and ground data processing and control systems.

The TRW/Raytheon team, applying years of collective expertise on missile warning programs, includes Aerojet, Agilent, Ball Aerospace & Technologies, Honeywell, Motorola, MRC, Nichols Research, PRA, Ryan, SciTec and Sparta.

Raytheon Co., based in Lexington, Mass., is a global technology leader that provides products and services in the areas of commercial and defense electronics, and business and special mission aircraft. Raytheon has operations throughout the United States and serves customers in 70 countries.
