基于时间间隔的观测卫星操作规划

Interval-Based Operation Planning for Observing Satellite

卫星的有效载荷的操作规划是卫星自主性的要求,目的是使卫星根据任务目标及有效载荷的当前状态,从有效载荷可选动作集合中自主选择有序的动作集合去完成任务。传统的行为规划技术在时间约束表示上有所不足,因此不能解决有效载荷的操作规划问题。本文介绍了一种基于时间间隔表示的规划方法,并将其应用于卫星的操作规划问题,可以很好的表示有效载荷操作规划中复杂的时间约束,通过一个简单的实例,给出了用这种方法在卫星操作规划问题中的成功应用。

Operation planning for payloads of observing satellites is the request of autonomous satellite technology, which (purpose) is autonomously select a set of actions and order these actions to complete the task according to the target, initial (states) of payloads and actions set satellite can execute. Classical behavior planning technologies are not enough to represent the time constraints, so they are not good for the operation planning problem. In this paper, interval-based representation is introduced and applied to the operation planning. This approach can represent the complex time constraints (between) satellite actions easy. A simple operation planning example is solved successfully (with) this approach.
