| 摘 要： | 不同历表计算天体视位置不同,对天文定向产生一定影响,影响程度随着观测天体的不同而不同。通过观测恒星、太阳、金星和火星进行天文定向时,历表对天文定向结果的影响可以忽略;通过观测月亮和土星进行天文定向时,必须考虑历表对天文定向结果的影响;通过观测木星进行天文定向时,在高精度要求下,必须考虑历表对天文定向结果的影响。

| Abstract: | Astro-geodetic orientation was affected by apparent place of celestial bodies calculated with different ephemeris. The influence degree was different along with the different observation objects. The effect could be igored while orientat- ing through the stars, the sun, Venus and Mars. It must be considered while orientating through the moon and Saturn. It was same for Jupiter in high precision request. |
