嫦娥一号卫星紫外月球敏感器

An Ultraviolet Lunar Sensor for CE-1 Spacecraft

探月工程是我国航天领域的又一项重大工程项目,嫦娥一号卫星是探月工程的第一步。嫦娥一号卫星首次采用了一种全新的光学姿态敏感器——紫外月球敏感器,实现在卫星环月飞行期间的姿态测量任务。紫外月球敏感器是一种以月球为姿态参考源的大视场成像式光学姿态敏感器,本文介绍其工作原理、功能与组成以及在轨飞行试验的相关情况。

CE-1, a lunar orbiting spacecraft, is part of the first phase of the chinese lunar exploration program. A novel optical sensor, ultraviolet （UV） lunar sensor, is employed in the CE-1 satellite. The UV lunar sensor is a wide-field of view （FOV） optical sensor which operates in the orbit around moon and provides the GNC subsystem with the pitch and roll information. This paper introduces the information of the UV sensor, including the principle, functions and the results of flight tests.
