摘要

为了进一步提高航天器的姿态控制精度，并对星识别算法进行分析，提出了一种有效的星图仿真方法。该方法利用不同纬度的相同视场，计算被观测恒星在电荷耦合器件(CCD)像面上的精确位置。根据星等、赤经、赤纬等特征，建立了导星目录数据库，工作迅速。仿真结果表明，与现有星图仿真方法相比，该方法能够获得较快的导航星选择速度，实现方便。

An Novel Effective Simulation Method of Star Atlas for Star Identification

In order to further improve the attitude control accuracy of the spacecraft and analysis the star identification algorithm, an effective simulation method of star atlas is proposed. This approach utilizes the same field of view in different latitude to calculate the exact position of observed stars in the charge-coupled device (CCD) image plane. Based on the magnitude, right ascension and declination features, the catalog database of guide stars is established and works rapidly. The simulation results show that the proposed method could obtain a fast speed of selection guide stars and can implement conveniently when compared to current star atlas simulation method.
