摘要
侦察卫星应用任务是指由侦察卫星完成的任务,构建任务模型是为了使用户提交的复杂多元的侦察任务表达更加清晰化,给后续的任务调度模型提供数据。通过对侦察任务的简单分析,结合规划域定义语言(PDDL)的特点,形成一种航天任务建模的新方法。针对侦察卫星应用任务的资源和时间约束等问题,采用对语言扩展的方法,通过给初始状态、目标说明和活动模型添加被扩展的谓词表达式来解决。最后,给出海上移动目标监视的案例,验证了建模方法的可行性。
Application missions of reconnaissance satellite represent the mission achieved by reconnaissance satellite. Purpose of modeling is to make complex mission referring by client more clearly and offering data to scheduling model. By analyzing characteristics of application missions of reconnaissance satellite and PDDL, this paper shows a new method of spaceflight mission modeling. Aiming at the representation of application missions of resource and temporal constraint, the approach for extending PDDL is proposed, which is established by appending extended predications into initial state, goal specification and action. Finally, a mode of a warning mission which is achieved by reconnaissance satellite is taken as example to validate feasibility of the method.
