摘　　要：在星光制导的空间飞行器中,为准确确定空间方位信息,提高导航系统的精度,对星跟踪器光学镜头设计提出很高的要求。针对精度要求,设计了一种新型星跟踪器的光学镜头,系统地阐述了星跟踪器的工作原理,通过光学设计及相差分析,使光学系统的畸变小于0.2%、轴向球差小于0.1,该设计满足用户对高精度天文导航系统的需求。In the star light guidance of space vehicles, the optical lens design requirements for star tracker are critical to determine accurately the spatial location information and to improve the accuracy of navigation system. A new type of star tracker optical lens system is designed according to the requirements and the operation principle is presented. With the optical design and difference analysis, the optical system distortion is less than 0.2%, the axial spherical aberration is less than 0.1, which can meet the demand for high-precision astronomical navigation system.
