The key constraints associated with high-resolution agile Earth-observation-satellite on-orbit usability are analyzed from the perspective of telecommand capacity,operationality,data acquisition/transmmision and power balance budget.A space-ground joint control scheme is pro-posed in this paper.The user missions operation for all kinds of Earth-observation-satellite is uni-fied through sending of goals instead of time-based command sequences.The utility efficiency of satellite costful power/storage/communication resources is dramatically improved through model-based dynamic planning instead of traditional static planning.The data acqusition/trasmmision running performace are remarkably exalted through on-board command scheduling instead of pre-set command sequences.Preliminary in-orbit testing and simulation for remote sensing satellite show that,the control interface complexity can be reduced by 94%,mission up-linking rate can be improved by 5 times,and meanwhile the utility efficiency of satellite costful resources is dra-matically improved.The proposed space-ground joint control scheme has great application poten-tial for high resolution earth observing system.%从任务注入、设备控制、信息获取、数据传输、能源平衡五个维度,分析了制约遥感卫星在轨可用性的瓶颈因素;提出新一代遥感卫星运控策略,采用"宏指令"取代"指令模板",提升卫星操控性;采用"动态规划"取代"静态规划",提升星载资源在轨使用效率;采用"自主指令序列优化"取代"被动执行预设指令",提升成像获取和数据传输任务的执行效率.某领域遥感卫星在轨测试和地面仿真表明,与传统运控模式相比,任务注入效率提升了约5倍,操作接口复杂度降低了约94%,并显著提升了星载能源、存储资源、对地数据传输资源的使用效率.
