摘　　要：文章首先简要介绍了"高分四号"卫星的主要性能指标和在轨运行情况,然后梳理了美国、欧洲等国家地球静止轨道高分辨率成像技术的发展现状。文章重点从卫星的轨道特性、多任务适应的工作模式、灵活的任务编排、实时动态监测、在轨长寿命几个方面总结提炼出"高分四号"卫星创新点;从谱段特性、成像体制、多功能一体化设计、高精度热控设计、高稳定性的结构一体化设计等多个方面分析了成像载荷的特点。最后,分析了地球静止轨道高分辨率成像卫星的发展趋势,展望了未来空间基础设施规划中计划实施项目的应用特点和应用领域。Firstly, the main performance and operation in orbit of GF-4 satellite are briefly described. Secondly, the development of the geostationary orbit and high resolution imaging technology programs of the United States and Europe are investigated. Thirdly, the GF-4 satellite innovations are summarized in regard to the satellite orbital characteristics, multitasking operating mode, flexible task scheduling, real-time dynamic monitoring, and long life in-orbit. And the characteristics of the imaging payload is analyzed in terms of spectral characteristics, imaging system, integrated multi-function design, high precision thermal control design, and integrated high stability structure design. Finally, the development trend of high resolution imaging satellite in geostationary orbit is given, and the application features and application fields of the implementation projects planned in the future space infrastructure planning are introduced.
