Lockheed Martin Begins GeoEye-2 Satellite Integration
Published: 2011-10-27 Source by: Original
October 25th, 2011, Lockheed Martin [NYSE: LMT] announced that it will begin integration of GeoEye's (NASDAQ: GEOY) next-generation, high-resolution Earth-imaging satellite, known as GeoEye-2, with the planned delivery of its integrated propulsion system to Lockheed Martin's Sunnyvale, Calif. facilities later this month.
The start of vehicle integration marks the on-schedule progress of installation and testing of satellite components and subsystems over the next several months in preparation for the delivery of ITT's high-resolution imaging payload early next year.
The integrated satellite structure and propulsion system serves as the structural backbone of the satellite and is essential in maneuvering GeoEye-2 to its final sun-synchronous orbit location, as well as conducting on-orbit repositioning maneuvers throughout its mission life.
GeoEye-2 is due to launch in early 2013. The satellite performance summary is as below:
