Galaxy 30 Quad-Band (L, C, Ku and Ka-band) Navigation/Communications Satellite orthrop Grumman was selected to build the Coverage Galaxy 30 satellite for Intelsat. This 1st Quad- North America and Global Band satellite will be the 11th satellite Northrop NGrumman has built for Intelsat and represents the first satellite in the Galaxy fleet replacement program. The satellite will be designed, built and tested at Northrop Grumman’s state-of-the-art satellite manufacturing facility in Dulles, Virginia, and will primarily serve video markets in North America. Galaxy 30 will be the 41st commercial spacecraft built by Northrop Grumman for customers around the world. Galaxy 30 will include a C-band payload for North Missions American coverage and a Ku/Ka payload covering the L-Band Navigation, C and Ku/Ka communications earth's surface with steerable spot beams. Galaxy 30 will also include a hosted L-Band global payload to support Customer the FAA’s WAAS GEO 7 program. Intelsat The GEOStar™ Heritage Northrop Grumman’s highly successful Geosynchronous Earth Orbit (GEO) communications satellites are based on the company’s GEOStar spacecraft platform, which is able to accommodate all types of commercial communications payloads and is compatible with all major commercial launchers. The company’s GEOStar product line includes the GEOStar-2 design, which is optimized for smaller satellite missions that can support up to 5.0 kilowatts of payload power. Northrop Grumman has also developed the higher-power GEOStar-3 spacecraft design, delivering the next increment of payload power for applications between 5.0 and 8.0 kilowatts, allowing Northrop Grumman to offer its innovative and reliable satellite design to the medium- class of communications satellites.
