Boeing Satellite Systems International is happiest when its products are far, far away. The company is a contracting unit for commercial and military spacecraft within the Boeing Space & Intelligence Systems division. It manufactures communications, meteorological, and research satellites. Boeing Satellite Systems International built the world's first geosynchronous communications satellite (Syncom) and estimates that it has manufactured about 40% of all the communications satellites in commercial service today (since its inception in 1961). Other satellite applications include cover radar mapping, satellite television, and national security. Contracts with the DoD constitute the majority of its revenues.
