摘要
研究了小卫星网络与学术型地面站网络的卫星任务调度(SRS,Satellite Range Scheduling)问题,分析出小卫星与学术型地面站网络任务调度的模型。针对学术型地面站网络与传统地面站网络相比下的低成本,非盈利,冲突通信窗口多等特点,分析其存在的冗余调度问题,并在时间粒度上提出公平性函数的定义并作出理论证明,用遗传算法进行调度优化。仿真实验说明了该方法在求解此类资源调度问题上是合理、有效的。
The satellite range scheduling between small satellites and academic ground station network is studied in detail, and the feature of network scenario and the model of SRS （ Satellite Range Scheduling） are also analyzed. Aiming at characteristics of low-cost, non-profit and increased conflict contact windows of academic ground network, the fair function in the time granularity is defined, and the simulation indi- cates that the theory is reasonable and effective in using genetic algorithm to find an optimal solution for this kind of resource scheduling.
