摘要:

在航空航天技术中,为了能够精确确定卫星的位置,卫星需要拍摄星空中的恒星,得到星像片,利用星像片上的信息来得到卫星的姿态信息,这些姿态数据在卫星定位中起到了重要的控制作用。基于矢量定姿原理和摄影测量中的共线方程,文中设计了一个通过星像片来获取卫星姿态信息的计算模型。同时通过计算恒星视位置,查阅星表数据库,改善了卫星姿态计算算法的精度。经过具体实验,姿态角计算可达到≤mq,mg≤08和mk≤5的精度。

关键词: 姿态角, 星像片, 摄影测量, 共线方程

Abstract:

In the aerospace technology, in order to achieve precise positioning of satellite attitude,we must be in the sky of stars shooting through the attitude information processing for satellite access to satellite photograph, the attitude data played an important role in satellite positioning. Vectororientation principle and collinear equation in photogrammetry based on the design of a high precision satellite photo attitude calculation model, calculation method and catalog database using the apparent positions of the stars, improves the ability of judging star is greatly improved, the photograph of the satellite attitude accuracy and reliable. After a specific experiment, the attitude angle can be calculated to be less than or equal to 0.8 and 5.

Key words: attitude angle, star photo, photogrammetry, collinear equation
