The US Air Force (USAF) space-based infrared system (SBIRS) team has completed final installations on the first geosynchronous (GEO-1) satellite.

The spacecraft has also completed its final factory confidence test in preparation for delivery to the launch site, Cape Canaveral Air Force Station, Florida, US, for a 2011 launch aboard an Atlas V launch vehicle.

SBIRS GEO-1 features sophisticated scanning and staring sensors, which will provide improved missile warning capabilities and support critical missions simultaneously.

Final installations included the spacecraft’s deployable light shade, solar arrays, thermal blankets and flight batteries.

Prior to shipment, the spacecraft’s flight software, designed to provide highly reliable command and control operations, will undergo final qualification testing and final readiness exercises.

The USAF SBIRS team includes prime contractor Lockheed Martin and the payload integrator Northrop Grumman.
