摘　　要：以天文自动导航系统的应用需求为目的,在传统星库构造方法的基础上,提出了一套较为完整、系统的、基于天区属性的导航星库和三角形星库的构造方法,并完成了工程实现。总结提出了源星库的构造方法,并利用天区归属的方法,为大视场三角形星库添加了天区属性信息,大大提高了星库对视场要求的适应性,节省了星库存储占用的内存空间,提高了天体识别的效率。According to the application of the strap-down astronomical attitude measure system,based on the former method,one integrated,systemic and aiming at the double observing field constructive method of star database has been put forward,and it has come to be practice.In this article,the conformation method of original star database has been put forward,and by the way of predefining the big sky area,the sky area information is added to triangle star database,the target rate of star identification and the applicability of star database have been improved,and EMS memory has been economized on.
