任务简介

Inmarsat-6 是总部位于伦敦的全球移动卫星通信运营商 Inmarsat 的第六代卫星。它由双重任务组成，旨在增强 L 波段和 Ka 波段 Global Xpress 服务。空客防务与航天公司已获得 Inmarsat 的合同，负责设计和开发前两颗 Inmarsat-6 (I-6) 移动通信卫星，打造其舰队中功能最全面的移动服务卫星。这两颗 I-6 卫星基于空客防务与航天公司的 Eurostar 平台，采用 E3000e 变体，该变体专门使用电推进进行轨道提升。卫星利用了这种电推进技术为双重有效载荷任务带来的质量减轻优势，并配备了异常大型的下一代数字处理有效载荷。 I-6 F1 和 F2 均携带一个大型 9 米孔径 L 波段天线和九个多波束 Ka 波段天线，具有高度的灵活性和连接性。新一代模块化数字处理器可在多达 8000 个信道上提供完全路由灵活性，并在 L 波段中为超过 200 个点波束提供动态功率分配。Ka 波段点波束可在整个地球盘面上进行转向，并具有灵活的信道到波束分配。

Inmarsat-6 is the sixth generation of satellites for the London-based global mobile satellite communications operator Inmarsat. It consists of a dual mission to augment both L-band and Ka-band Global Xpress services. Airbus Defence and Space has been awarded a contract by Inmarsat to design and develop the first two Inmarsat-6 (I-6) mobile communications satellites, creating the most versatile mobile services satellites in its fleet. The two I-6 satellites are based on Airbus Defence and Space's Eurostar platform in its E3000e variant, which exclusively uses electric propulsion for orbit raising. The satellites take advantage of the reduction in mass that this electric propulsion technology enables for a dual payload mission, with an exceptionally large next generation digitally processed payload. I-6 F1 and F2 both carry a large 9 m aperture L-band antenna and nine multibeam Ka-band antennas, and feature a high level of flexibility and connectivity. A new generation modular digital processor provides full routing flexibility over up to 8000 channels and dynamic power allocation to over 200 spot beams in L-band. Ka-band spot beams are steerable over the full Earth disk, with flexible channel to beam allocation.
