【摘要】 本文提出了基于星体模式识别的三星星图划分算法。论文工作主要包括以下两个步骤:第一,选取星空中一圆形区域,并将该区域划分为四个部分,分别对这四个部分进行划分,使每个部分都可以捕获三颗导航星。第二,采用三星星图划分法结合三角形星体模式识别法作为星体识别模式,分析了在不同星敏感器精度情况下的星图识别率。仿真分析表明:相对于两星星图划分算法,该算法对星敏感器精度要求更低,并具有更高的星图识别率。更多还原

【Abstract】 In this paper,a three-star-star-map divi(?) posed based on the star pattern recognition.The algorithm presented in our paper is mainly compose(?)teps.Firs(?)area of the sky is selected and separated into four regions,and the four regions are divide(?)ectively to ensure ■ree navigation stars can he found in each region. Secondly,the three-star-star-map dividing algorithm associated with the approach of triangle star pattern recognition is chosen as the star recognition mode,and the star-map recognition ratios are analyzed under the condition of different precision of star sensors. Simulations show that the method requires less precision of star sensors and is more efficient than the present two-star-star-map dividing algorithm.更多还原
