用于未来月球探测的ILOM技术现状

Present Status of ILOM for Future Lunar Missions

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。

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 1milliarcsecond.We will make test observations on the ground in order to evaluate overall characteristics with the target accuracy of better than 0.1arcseconds.
