摘要
针对应急任务突发性强、时效性要求高的特点,结合高分多模卫星的多角度成像模式、指令优先级设置、任务重置以及星上区域提取数据处理等,应用考虑测控窗口及数传窗口的滚动规划策略。针对以上需求或特点对应急任务的规划流程进行了设计,通过高分多模卫星在轨验证表明:该卫星的相关特性能够增加应急任务的执行成功率、提高有效数据的获取率、缩短数据回传所需的时间。
Emergency tasks have characteristics like suddenness and high-efficiency requirements.The GFDM-1 satellite has several favorable features to deal with emergency tasks,including multi-angle imaging mode,priority setting of telecommands,task reset,on-orbit data processing and data transmission to relay satellites.Considering rolling schedule strategy of measurement-controlling windows and data transmission windows,emergency tasks schedule process is designed.Through actual verification with GFDM-1 satellite,increased success rate in task execution,improved access to effective data,shorted the time for data playback can be achieved.
