Summary:The invention discloses a spinor-based star sensor posturing method and belongs to the technical field of surveying and mapping science and technology. The method includes: extracting star point between fixed star image and a stat catalogue, and connecting the start points with a same linear name; using spinor to respectively connect to form a same-name straight line; using the spinor to respectively express a same-name straight line in fixed star image and navigation star catalogue; according to a rule that the fixed star image and the star catalogue are in a same-name linear line, building acollinear condition quotation of spinor; adopting a minimum square law adjustment method to solve star sensor posture. Scale zooming of space straight line can be expressed by utilizing spinor, so that a star sensor posture determining model high in inside reliability is built, and star sensor posturing accuracy is higher when compared with conventional methods. 本发明公开种基于旋量的星敏定姿方法，属于测绘科学与技术领域。提取恒星星象的星点和星表中与之同名星点，并将其分别连接成同
