摘要: 2021 年9 月成功发射的高光谱观测卫星 (高分五号 02 星) 是我国高光谱遥感能力的重要标志。该卫星定量化 程度高, 装载的7 台载荷中, 有6 台具有在轨定标能力, 卫星除偏航90°场地定标和偏航太阳定标的工作模式外, 还设计 了姿态机动对月定标模式。主要介绍了高光谱观测卫星的姿态机动模式和对月定标方案, 详细阐述了月球运动规律、 机动对月定标的姿态机动模式、对月定标的观测窗口和角度, 并总结了月球定标的工作流程, 分析了对月定标过程的 姿态指向精度、光照条件、星敏视场及卫星热控影响。分析结果表明, 在对月定标过程中, 卫星能够很好地适应机动过 程带来的光照、外热流等外部环境的变化, 指向精度可以满足对月定标观测需求。

Abstract: The hyperspectral observation satellite (Gaofen-5(02) satellite), successfully launched in September 2021, is an important indicator of hyperspectral remote sensing capability of China. The satellite has a high degree of quantification, with 6 out of 7 payloads having in-orbit calibration capability. In addition to the working modes of yaw 90° site calibration and yaw sun calibration, an attitude maneuver calibration mode to the moon has also been designed for the satellite. This paper mainly introduces the attitude maneuvering mode and lunar calibration scheme of hyperspectral observation satellites, elaborates on the law of lunar motion, the attitude maneuvering mode of maneuvering to lunar calibration, the observation window and angle of lunar calibration, and summarizes the workflow of lunar calibration, and analyzes the attitude pointing accuracy, illumination conditions, star-sensitive field of view and satellite thermal control of the lunar calibration. The analysis results show that in the process of maneuvering calibration to the moon, the platforms and payload systems can adapt well to the changes of the external environment such as illumination and external heat flux, and the pointing accuracy of the satellite can meet the observation requirements of lunar calibration.

Key words: hyperspectral observation satellite, attitude maneuver, lunar calibration, lunar phase angle
