| Abstract: | This paper introduced an algorithm, by which aircraft attitude can be acquired through observation of two stars utilizing star tracker fixed on aircraft itself. Then the corresponding coordination is established, and the relation, between observation angle of stars and the quaternion describing aircraft attitude, is also derived. |
