摘要
提出了一种新的微小卫星系统任务规划方法,解决微小卫星任务遥控时资源受限的问题;通过GQM建模将卫星调度任务进行度量元素量化,量化过程中兼顾公平性和合理性,并以任务完成度和卫星功耗作为目标进行评估;通过1000次卫星过顶仿真,40项建模任务的平均完成度达到0.63,每次过顶卫星功耗方差不超过40,证明新方法较传统方法在平稳功耗条件下任务完成度得到有效提升,具有良好的实用性和指导性,适用于自动任务规划和调度的自主运行地面站系统。
In this paper, a new task scheduling method is proposed to deal with the telecontrol problem of resource--constrained micro-- satellite. This method is based on the GQM model, which can quantify the priority of micro--satellite tasks fairly and evaluate the complete- ness and power consumption of the tasks reasonably. Over 1000 times simulation of satellite overhead, the average degree of completion of the 40 modeling tasks reaches 0.63, and the power consumption variance of each satellite overhead is not more than 40. The simulation result shows that this method can not only ensure the completeness of the tasks, but also guarantee the steady power consumption of the micro-- satellite. The method has good practicability and guidance and is suitable for the automatic ground station.
