任务简介
TIBA-1 是一颗面向埃及政府的地球静止通信卫星，由泰雷兹阿莱尼亚宇航公司（TAS）和空中客车公司联合开发。作为主导合作伙伴，TAS 设计并建造了通信有效载荷，具有 Ka 波段双任务能力，用于安全宽带通信。空中客车防务与航天公司提供了 Eurostar E3000 平台，并完成了卫星的组装和测试。TIBA-1 设计在轨服务寿命超过 15 年，发射质量 5600 千克，电力能力高于 9 千瓦。 Inmarsat-5 F5（Global Xpress-5 或 GX-5）是 Inmarsat 的甚高通量卫星（V-HTS），将提供覆盖中东、欧洲和印度次大陆的服务。其有效载荷将完全集成到 Inmarsat 当前的 Global Express 高速网络中。Inmarsat-5 F5 卫星基于泰雷兹阿莱尼亚宇航公司升级的 Spacebus 4000 B2 平台，配备 72 个 Ka 波段波束。设计寿命为 16 年，发射质量 4007 千克，有效载荷功率约 6.8 千瓦。
原文
TIBA-1 is a geostationary communications satellite for the Government of Egypt developed jointly by Thales Alenia Space (TAS) and Airbus. TAS, the leading partner, designed and built the communications payload, featuring a dual mission in Ka-band for secure and broadband communications. Airbus Defence and Space supplied the Eurostar E3000 platform and assembled and tested the spacecraft. Designed to remain in service in orbit for more than 15 years, TIBA-1 will have a launch mass of 5600 kg and an electric power capability of higher than 9 kW. Inmarsat-5 F5 (Global Xpress-5 or GX-5) is Inmarsat's very high throughput satellite (V-HTS), which will offer services covering the Middle East, Europe and the Indian sub-continent. The payload will be fully integrated into Inmarsat’s current Global Express high-speed network. Inmarsat-5 F5 satellite is based on Thales Alenia Space’s upgraded Spacebus 4000 B2 platform and will be fitted with 72 Ka-band beams. With a specified design life of 16 years, it will weigh 4007 kg at launch and will offer payload power of about 6.8 kW.
