摘要
本文提出仅用星敏感器进行自主导航定位方法。通过大气折射数据确定飞行器高度，用星敏感器间接测量飞行器到地心的方向矢量，从而确定飞行器在地球直角坐标系中三维坐标。
A primary investigate is given in this paper about an accurate position method of autonomous navigation only using the stellar sensor, and it can determine the altitude of aerocraft according to data about atmosphere refraction, and can indirecdy measure direction vector from aerocraft to earth core using stellar sensor, and can consequendy confirm three-dimensional coordinate of aerocraft in rectangular coordinate system of earth.
