[Satellite Today 12-23-08]  A team led by Lockheed Martin has completed and delivered the high-performance communications subsystem for the geosynchronous orbit (GEO-2) spacecraft core structure and propulsion subsystem to the U.S. Air Force, Lockheed Martin announced Dec. 22.
    The announcement is a milestone in Lockheed Martin’s contract with the U.S. Air Force to develop the Space-Based Infrared System (SBIRS). The communications subsystem will deliver anti-jam, survivable communications and data 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.
