Company to Provide System to Monitor the Performance of SBIRS-High, A Satellite-Based Ballistic Missile Detection System

Integral Systems, Inc.
today announced that Northrop Grumman Space Systems Division in
Azusa, CA has awarded the company the contract for development of the SBIRS-
High (Spaced-Based Infrared System) Payload Diagnostic System (SPDS). SBIRS-
High is the high-Earth orbiting component of the U.S. Air Force’s Space Based
Infrared System, a fleet of advanced satellites that will become the primary
initial warning system for ballistic missile attacks. SPDS is based on
Integral’s EPOCH 2000(TM) command and control software product line, which is
used worldwide for satellite and payload integration, testing, and mission
operations. When completed, SPDS will monitor the satellite’s instrument
payload to determine its performance, detect anomalies, and when necessary
generate corrective actions.

“We are very excited and very proud that our product solutions are now a
part of a system that is so vital to our national defense,” said Donald Mack,
Vice President of Integral’s Integration and Test Division. He added, “Our
customer recognized that EPOCH’s capability and our unmatched experience will
result in a system that will reduce development risk and cost.”
