In November 1991, PanAmSat Corporation ordered three Hughes HS-601 model PAS (PanAmSat) satellites from Hughes Space and Communications Company. The satellites provide video services for program distribution and syndication; data services for business applications; and services for video, radio, data and telephone transmission. They were placed over the Pacific, Atlantic and Indian oceans, respectively. In August 1993, PanAmSat ordered a fourth satellite, to be used as a spare. The spare was pressed into service to replace the first PAS-3 spacecraft, which was lost during a launch vehicle failure.
