摘　　要：针对高轨卫星在无地面测控站支持下难以实现高精度自主导航,卫星的自主生存能力不足的问题,文章提出一种利用地球紫外波段和恒星可见光波段为卫星进行自主导航的技术并进行了在轨验证,该导航方法利用视场1观测恒星可见光波段,视场2观测地球紫外波段。视场1利用星敏感器全天球识别算法识别所有恒星星像,识别结果的光轴指向作为恒星矢量;视场2被用来对地球紫外波段轮廓成像,计算得到地心矢量在卫星本体坐标系中的方向,通过高精度的系统偏差标定,实现了目前国内较高精度的高轨卫星天文导航应用。In response to the problem of improving the autonomous survival and mission capabilities of satellite,and ensuring high-precision autonomous navigation tasks for future high orbit satellites without ground measurement and control station support.a method for autonomous navigation of satellite using the Earth ultraviolet and stellar visible light bands is proposed in this paper.This method uses field of view 1 to observe the stellar visible light bands and field of view 2 to observe the Earth ultraviolet bands.Then,field of view 1 is used to recognize all stellar images using the global recognition algorithm,and the optical axis direction of the recognition is used as the stellar correction,field of view 2 is used to image the contour of the Earth ultraviolet band and calculate the direction of the Earth center vector in the satellite coordinate system.Through the high-precision system deviation calibration,the current domestic high orbit autonomous navigation application has been achieved in high-precision.
