 针对遥感卫星的成像任务规划问题,按照任务重要性的不同,提出了两阶段调度策略,并设计了两个时间窗口选择规则。以星上存储资源优化为目标,利用地面站的下传活动将整个规划过程分为较小的调度区间,提出了可用存储空间上界估计算法计算每个调度区间的可调度存储资源容量,以此为基础对问题进行了简化,并给出了基于规则的启发式求解算法。实验结果表明,该算法是有效的。 更多还原

【Abstract】 Mission planning problem of remote sensing satellite is investigated here.According to the difference of mission’s importance,a two-step scheduling strategy is proposed,and two rules of selecting time window are designed.All the scheduling algorithms based on the rules for two steps are also designed.According to the downlink activities of satellite,the whole planning cycle is divided into several intervals,and an algorithm to compute the upper bound of spare capacity of Solid State Recoder(SSR)... 更多还原
