Lockheed Martin Achieves Key Integration Milestones on Second SBIRS Missile Warning Satellite
SBIRS will provide early warning of ballistic missile launches and support other missions simultaneously, including missile defense, technical intelligence and battlespace awareness.
The GEO-2 bus is the structural foundation of the satellite and includes an integrated propulsion system as well as other critical subsystems for communications, attitude control, thermal control, command and data handling. The GEO-2 payload features a scanning sensor that will provide for short revisit times over its full field of view and a staring sensor that can be tasked for dedicated stare operations over smaller areas.
“The team has been diligent in incorporating lessons learned during the groundbreaking integration and test of the first GEO space vehicle,” said
The successful GEO-2 payload and bus integration allows the SBIRS team to begin system level environmental and acceptance testing in preparation for launch in 2011.
The SBIRS team is led by the Space Based Infrared Systems Wing at the U.S. Air Force Space and Missile Systems Center,
Lockheed Martin’s SBIRS contract includes the two highly elliptical orbit (HEO) payloads now on-orbit, two geosynchronous orbit (GEO) satellites, as well as ground-based assets to receive and process the infrared data. The team was recently awarded a 1.5-billion contract for the third HEO payload, the third GEO-3 satellite and associated ground modifications. A contract to include a fourth HEO payload and potential fourth GEO satellite is expected to be awarded later this year.
