The development of state-of-art GEO civil optical earth observation satellites with mid-high resolution is investigated, including COMS, GEO-Africa, GEO-Oculus, etc. The mission and main functions of these satellites are analyzed. The system level design and main technology approach of these satellites are summarized and compared. Finally, several issues that are important in GEO mid-high resolution civil optical earth observation satellites technology are discussed, such as selection of focal detector, high stability attitude control, jitter rejection, heat management in the night, etc. The research results could be instructions to the development of China's GEO civil optical earth observation satellites with mid-high resolution.%调研了国外地球静止轨道(GEO)中高分辨率民用光学对地观测卫星的发展情况,其中包括“通信海洋-气象卫星”(COMS)、GEO-Africa和GEO-Oculus等卫星；分析了卫星的任务范围和主要功能；对卫星总体设计方案和采用的主要技术途径进行了归纳和对比.对发展GEO中高分辨率民用光学对地观测卫星需要注意的探测器选型、高稳定度姿态控制、微振动抑制、夜晚阶段的热控等相关问题进行了分析,可为中国发展同类卫星提供参考.
