用于未来月球探测的ILOM 技术现状

Present Status of ILOM for Future Lunar Missions

摘要: 使用面包板模型和仿真方法,在实验室内研究月球指向就位测量望远镜(ILOM)的基本特征,如望远镜星像中心点位置精度、温度效应、倾斜以及地面震动的影响。使用这个技术预期在月球表面观测月球自转时可以达到1ms的精度。将在地面上开展测试验证观测以全面评价达到优于0.1″观测精度目标所需条件和特征。

Abstract: We investigated basic characteristics of the telescope for In-situ Lunar Orientation Measurement (ILOM), such as the centroid accuracy and the effects of temperature change, tilt and ground vibrations, by laboratory experiments using a Bread Board Model and by simulations. We have a prospect to observe the lunar rotation on the lunar surface with the accuracy of 1 milliarcsecond. We will make test observations on the ground in order to evaluate overall characteristics with the target accuracy of better than 0.1 arcseconds.
