Lockheed Martin has completed a baseline integrated system test (BIST) on the first Space-Based Infrared System (SBIRS) geosynchronous orbit spacecraft, the company announced April 30.
The completion of the test clears the way for integration of the solar arrays, deployable light shade and thermal blankets and then the acoustic and pyroshock testing, where the integrated space vehicle will be subjected to the maximum sound and vibration levels expected during launch into orbit.
The satellite is designed to provide new missile detection and surveillance capabilities for the nation and is scheduled to be launched in late 2009.
