摘要
基于FK5及DE405星表数据文件,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,提出高精度恒星视位置计算数学模型。精度分析表明,该模型计算精度优于《航海天文历》及现有天文导航计算自动化软件,是可行的。
Based on FK5 and DE405 ephemeris, the paper analyzed the influence of relativity, precession, nutation and aberration on apparent position calculation of star. Astronomy vector treatment was employed. The automatic calculation of star apparent position was realized by program language VC ++. The calculation result of the model is more accurate than the calculation results of nautical almanac and other calculating program. 2 tabs, 2 figs, 7 refs.
