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.
