Lockheed Martin has achieved a major milestone with completion and delivery of a sophisticated, high-performance communications subsystem integral to the infrared payload of the first Space-Based Infrared System High (SBIRS High) geosynchronous orbit (GEO) satellite.
SBIRS High, the nation’s next-generation missile warning system and a critical element of missile defense, will feature a communications subsystem successfully developed and tested at Lockheed Martin’s facilities in Newtown, Pa., and delivered to its Space Systems Company in Sunnyvale, California. The communications subsystem will serve a key role in the SBIRS mission by delivering anti-jam survivable communications from the infrared payload to the warfighter and provide worldwide coverage of missile launch detection and defense data. The subsystem also provides secure command and control of the satellite by continuous interaction with ground stations.
Over the next several months, Lockheed Martin Space Systems, the SBIRS High prime contractor, and Northrop Grumman Electronic Systems, the payload provider, will integrate the subsystem into flight configuration and continue component installation and preparation activities leading to the start of final assembly, integration and test later this year.
When fully operational, SBIRS High will comprise two payloads in highly elliptical orbit (HEO), four satellites in geosynchronous orbit (GEO), as well as fixed and mobile ground-based assets to receive and process the infrared data. The team has completed the HEO payloads and is on track to begin final integration and test of the first GEO satellite later this year in preparation for launch in fiscal year 2008.
