摘要
针对高分多模卫星多有效载荷、大数据量、复杂敏捷成像等特点,根据多用户对图像质量、成像模式、获取时效性等应用需求及设计约束,提出了高分多模卫星发射入轨、轨道控制、正常运行、任务执行等各工作模式。其中,针对任务执行模式的敏捷成像模式、数据存储与传输模式、特定区域快速获取模式进行了详细论述。在轨测试结果表明:高分多模卫星工作模式设计正确、合理,卫星任务执行效率高、运行稳定,可以满足用户使用要求。
The characteristics of GFDM-1 satellite include multi-payload-loaded,large data amount and complex agile imaging modes,etc.Based on the application requirements from multi consu￣mers and the design restrictions,all kinds of operating modes are presented,including launch-into-orbit mode,orbit control mode,normal operation mode and task execution mode,etc.Among these modes,the agile imaging mode,data recording and transmission mode and quick acquisition of the specific area mode of the task are discussed in detail.The on-orbit test results show that the design of operating mode for GFDM-1 satellite is correct and logical,the mission is highly efficiently completed and is working steadily,and the application requirements of the consumers can be primly met.
