摘　　要：针对一类光学小卫星成像调度的应用需求,综合考虑星地等各种资源的载荷使用约束,设计实现了一个成像调度系统。详细分析了载荷约束,针对约束特点,提出了五阶段系统执行流程,并重点介绍了各阶段的关键技术,包括基于成像约束图的观测动作生成算法和基于背包模型的数传动作生成算法。最后给出了应用实例和实验结果,表明了系统的适用性和可行性。该系统已经成功应用于某在轨卫星的日常规划中。To solve the imaging scheduling needs for a small optical satellite, a system was designed and implemented, which considered the constraints of both the satellite and the ground stations. Thefive phase system procedure was proposed based on the complete analysis. The key technique of the five phases was focused on, especially the observing action based on Constrained lmaging Graph model and transmitting action based on Knapsack model After that, the instance and the experiment results were given, which show that the method is feasible and effective. The system has been used by one satellite system which is on use.
