任务简介
1991年11月，PanAmSat公司向休斯空间与通信公司订购了三颗休斯HS-601型PAS（PanAmSat）卫星。这些卫星为节目分发和联合播出提供视频服务；为企业应用提供数据服务；以及为视频、广播、数据和电话传输提供服务。它们分别部署在太平洋、大西洋和印度洋上空。1993年8月，PanAmSat订购了第四颗卫星，作为备用星。该备用星后来被投入使用，以替换因运载火箭故障而丢失的第一颗PAS-3卫星。

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.
