基于载荷共基准的高分七号卫星构型设计与验证

Design and Verification of GF-7 Satellite Configuration Based on Common Reference Payload

针对高分七号卫星载荷质量大、数量多,在轨工作环境要求高,总装时间短等特点,以一体化支架为整星成像测绘任务基准,采用载荷共基准的卫星构型布局方法及模块化设计原理,提出“π”平台、整星总装构型和星敏感器载荷一体化安装构型总装设计方案,并得到了卫星研制实践验证。经高分七号卫星在轨运行,结果表明:卫星构型总装方案设计合理可行,能满足卫星需求,可为我国后续高分辨率国土测绘卫星的构型、总装设计提供参考。

In view of the characteristics of GF-7 satellite, such as high-weight payload, high requirements for on-orbit environment and the short assembly time,an integrated bracket is proposed as the reference of imaging. Based on the configuration layout of common reference payload and the principle of modularization, a configuration layout consisting of the "π" scheme, the whole satellite configuration of service module and payload module design, and the star sensors integrate on the double-line array tridimensional mapping camera design is put forward and verified, The on-orbit operation results of GF-7 satellite show that the configuration layout is reasonable and feasible, which can meet the requirements of satellite and provide a reference for China’s next high resolution satellite configuration layout.
