摘要
研究了一类过站时间较长的可见光对地观测卫星数传调度问题.通过分析该类卫星工作特点及数据传输约束条件,利用其长可见时间窗特性建立一种考虑多数传模式组合的约束满足模型,在此基础上给出了基于最大收益损失比的卫星数传调度算法.仿真实验结果表明该方法能够有效解决该类卫星数传调度问题.
According to data transmission scheduling problem of an optical Earth Observation Satellite （EOS） with long time window, a new method is presented. Firstly, the constraints and characteristics of EOS are analyzed. Then, a mathematical model that considers multiform data transmission mode coexistence utilizing the feature of a long time window is proposed. Meanwhile, this paper presents a scheduling algorithm for EOS based on the maximal ratio of gain and loss. Finally, extensive experiments are implemented which verify the correctness and practicability of our approach.
