环境减灾-1A、1B卫星研制综述

A Summary of HJ-1A/1B Satellite Development

环境与灾害监测预报小卫星星座-—环境减灾-1A、1B卫星经历了方案阶段、初样阶段、正样阶段的研制工作,研制中解决了星座设计与优化、全新载荷的研制难题,克服了主动段时间长和任务与接口要求变化大等问题,积累了丰富的经验和教训,可以为其它型号研制提供借鉴。

Environment and Disaster Monitoring Satellite Constellation （HJ-1A/1B） has experienced the preliminary design, engineering model and flight model phases. The development of HJ- 1A/1B Satellite Constellation has figured out all the know-hows such as constellation design, system improvement and R＆D of new payloads. A lot of experience are drawn from its R^D, such as how to deal with over-long launching phase, the diverse mission and interface requirements. Successful on-orbit flight of HJ-1A/1B could provide much valuable information to the development of other satellites.
