Tiantong-1-02
中国航天科技集团 (CASC) · 长征三号乙增强型 (CZ-3B/E) · 2 号发射工位 (LC-2)
任务简介
天通一号02星由中国航天科技集团（CASC）下属的中国空间技术研究院（CAST）设计，该研究院专门从事航天器设计。卫星将由CASC的另一家子公司——中国卫星通信集团有限公司运营，该公司拥有约十颗通信卫星，如中星和亚太星。 天通一号02星是中国首个移动通信网络的第二颗卫星。 它采用中国DFH-4卫星平台，据其制造商CAST称，与同系列其他卫星相比，其有效载荷质量利用率最高。 该项目于2010年启动，起因是2008年四川地震中几乎所有地面通信网络瘫痪。当时中国没有移动通信卫星，因此不得不向国外租用服务，如欧洲的Inmarsat，用于其救援队伍。

Designed by the CAST Institute (China Academy of Space Technology), a subsidiary of the Chinese aerospace group CASC and specialized in spacecraft design, the Tiantong-1 02 satellite will be operated by China Satellite Communications Co. Ltd, another CASC subsidiary which owns about ten communication satellites such as the ChinaStar and APStar. Tiantong-1 02 is the second satellite of China's first mobile communication network. It uses a Chinese DFH-4 satellite platform, and, according to its manufacturer CAST, has the highest payload mass utilization rate compared to other satellites of the same family. The project was launched in 2010 following the 2008 earthquake in Sichuan, where almost all ground communication networks were paralyzed. China had no mobile communication satellites at the time, so it had to lease services from foreign countries, such as Inmarsat in Europe, for its rescue teams.
