SUNNYVALE, Calif., 2 May 2006. The Lockheed Martin has announced that its team working on the Space-Based Infrared System (SBIRS) has delivered a critical payload subsystem and associated software for the program's first geosynchronous orbit (GEO) satellite.
SBIRS, with scanning and staring sensors, will provide the nation with missile warning capabilities, as well as support such missions as missile defense, technical intelligence, and battlespace characterization.
The software will provide for the control and testing of the spacecraft's Pointing and Control Assembly (PCA), which were delivered to Northrop Grumman Electronic Systems, Azusa, Calif., for payload integration and testing.
The GEO PCA features Lockheed Martin's patented reaction-less gimbal system, which allows the satellite to scan an area of interest for infrared activity without interfering with the satellite's ability to stare at another area.
The completed payload is scheduled to be delivered to Lockheed Martin's facilities in Sunnyvale, Calif., in mid-2007 for final spacecraft assembly, integration, and test in preparation for launch in fiscal year 2008.
