摘要
针对多星对地观测系统联合任务规划问题,考虑卫星载荷具备连续侧摆能力和多种数据压缩模式的新特点,构建了多星联合任务规划模型,在此基础上设计多星联合任务规划和数传调度算法框架,实现了卫星连续侧摆成像规划算法和基于任务优先级的数传任务调度算法,最后采用实际算例进行试验,结果表明文章提出的多星联合任务规划方法能在提高完成任务数量的同时降低卫星资源消耗,满足实际应用需求。
In the multi-satellite scheduling system of the earth observing system, considering the satellite has the capability of continuous side shift and multiple data compression rate, the multi-satellite scheduling model was constructed. Based on this model, a new scheduling and data transmission method for multi-satellite was designed and implemented, including an imaging scheduling algorithm considering continuous side shift and a data transmission method considering task priority. The experiment results show that the method can reduce the cost and meet the application requirements.
