任务简介
Eutelsat 7C 基于全电推进版本的 SSL-1300 卫星平台。该卫星配备 44 个工作 Ku 波段转发器，将与 Eutelsat 7B 共位，释放 Eutelsat 7A 至另一轨道位置。这一改进的双卫星星座将使 Eutelsat 能够优化两颗卫星的资源，增强覆盖灵活性和连接性，将东经 7 度邻域提升至新水平。通过将撒哈拉以南非洲的容量从 22 个转发器几乎翻倍至 42 个，还将为数百个额外的数字频道腾出空间，以支持该地区快速扩张的电视市场。Eutelsat 7C 还将配备一个波束，为欧洲、中东和中亚的政府服务提供增强容量，以及一个可转向波束，覆盖东经 7 度可见的任何区域。 AT&T T-16 基于 Astrium 的 Eurostar-3000 平台。该卫星的有效载荷包括 Ku 波段和 Ka 波段的高功率转发器。它将运行于西经 100.85 度。
原文
Eutelsat 7C is based on an all-electric propulsion version of the SSL-1300 satellite platform. Equipped with 44 operational Ku-band transponders, the new satellite will be copositioned with Eutelsat 7B, releasing Eutelsat 7A to another orbital location. This improved two-satellite constellation will enable Eutelsat to optimise resources across both satellites, with enhanced coverage flexibility and connectivity set to take the 7° East neighbourhood to a new level. By almost doubling capacity over Sub-Saharan Africa, from 22 to 42 transponders, it will also make room for several hundred additional digital channels to support the region’s fast expanding TV market. Eutelsat 7C will also be equipped with a beam providing enhanced capacity for government services over Europe, the Middle East and Central Asia, and a beam that can be steered to cover any region visible from 7° East. AT&T T-16 is based on Astrium’s Eurostar-3000 platform. The satellite has a payload comprising of high power transponders in Ku-band and transponders in Ka-band. It will operate from 100.85° West.
