论文摘要
空间任务的特征是长距离，困难或无法获得的沟通以及高昂的运营成本。此外，近年来的复杂性一直在不断增长。因此，提高太空运营商的自主权是一个有吸引力的目标，可以通过较低的成本提高任务奖励。本文提出了一个机载调度程序，该调度程序集成了用于任务自治的机载软件框架。给定一组活动，它负责根据每个活动的优先级，订单约束和资源消耗来确定每个活动的起始时间。提出的调度程序基于线性整数编程，依赖于使用分支和切割求解器的使用。该技术已在地球观测方案上进行了测试，将其性能与最先进的调度技术进行了比较。
Space missions are characterized by long distances, difficult or unavailable communication and high operating costs. Moreover, complexity has been constantly increasing in recent years. For this reason, improving the autonomy of space operators is an attractive goal to increase the mission reward with lower costs. This paper proposes an onboard scheduler, that integrates inside an onboard software framework for mission autonomy. Given a set of activities, it is responsible for determining the starting time of each activity according to their priority, order constraints, and resource consumption. The presented scheduler is based on linear integer programming and relies on the use of a branch-and-cut solver. The technology has been tested on an Earth Observation scenario, comparing its performance against the state-of-the-art scheduling technology.
