| 摘 要： | 成像敏感器根据月像来确定卫星对月姿态角。分析了月球光学系统成像模型以及卫星两轴姿态角与月像边缘曲线方程的关系，利用分析结果并结合月像边缘点的曲线拟合提出了一种新的卫星对月定向姿态确定方法。此算法克服了非零姿态月像边缘的非圆现象并且在部分月像下也可完成姿态确定，仿真工作显示了新算法的有效性。

| Abstract: | Imaging sensor determinate the aircraft attitude by lunar image's analysis.This paper analyzed the imaging mode of Luna and the relations between attitude angles and lunar image edge's equation.Based on the relation and curve fitting method,a novel attitude-determinated algorithm is put forward.This method solved the lunar image un-circled problem when nonzero attitude and was useful when not full moon.The simulation results show this algorithm is effective. |
