| 摘 要： | 任务间卫星观测姿态调整时间是敏捷成像卫星任务规划最为重要的一个约束。对姿态调整时间的影响因素进行分析,建立空间运动学模型计算任意时刻卫星对目标的观测摆角。在此基础上,给出一种姿态调整时间的计算方法。通过仿真实验,对不同调姿模式和调姿开始时间条件下姿态调整时间的变化及其对最早可观测时间的影响进行了分析,旨在为敏捷成像卫星任务规划提供支持。

| Abstract: | Attitude changing duration of the satellite observation between tasks is one of the most important constrains for the tasks scheduling of an agile imaging satellite.In this article,factors affecting the attitude changing duration are analyzed.A kinematic model is established to compute the observing angle of the satellite at any moment.Then,a method is proposed to acquire the attitude changing duration.The influence of the duration to the earliest visible time,considering different attitude changing mode and beginning time,is analyzed by the simulation.The conclusion of this research supports the tasks scheduling of the agile imaging satellite. |
