摘　　要：基于SKY2000星表数据，考虑相对论效应、岁差、章动、光行差影响，采用天文矢量处理方法，给出一整套多颗恒星视位置高精度同步计算数学模型。在优化计算流程的基础上，采用VC＋＋编程实现了多颗恒星视位置同步计算的自动化，精度、速度分析表明，精度优于《航海天文历》及现有天文导航计算自动化软件，计算速度较之传统方法有了显著提高。The article is based on the data included in the SKY2000,considering the effect of relativity, precession, nutation and aberration .In the article the astronomy vector technique is adopted .The article bring forward a suit of the synchronous calculating models which are used to give the precise apparent position of many stars. On the basis of optimizing calculation process, adopted Visual C＋＋ and realized the automatization of the synchronous calculating apparent position of many stars .The precision and rapidity analysis indicate that the precision which this article gave is much higher than that of 《Nautical Almanac》 ,the rapidity of compute excelled traditional method.
