WGS satellites are important elements of a new high-capacity satellite communications system providing enhanced communications capabilities to our troops in the field. WGS has 19 independent coverage areas, 18 of which can be positioned throughout its field-of-view. This includes eight steerable/shapeable X-band beams formed by separate transmit/receive phased arrays; 10 Ka-band beams served by independently steerable diplexed antennas; and one transmit/receive X-band Earth-coverage beam. WGS can tailor coverage areas and connect X-band and Ka-band users anywhere within its field-of-view. The X-band phased array antenna enables anti-jam functionality without sacrificing performance.Launch Notes:
WGS-9 will mark the seventh flight of the Delta IV in the Medium + (5,4)configuration; all launches in this configuration have delivered WGS missions to orbit. This mission also will be the 35th launch of the Delta IV since its inaugural launch in 2002.Launch Updates:
