摘要
为发展月球和行星探测,美国喷气推进实验室(Jet Propulsion Laboratory,JPL)、法国天体力学与历算研究所(Institut de Mécanique Céleste et de Calcul deséphémérides,IMCCE)、俄罗斯科学院应用天文研究所(Institute of Applied Astronomy of the Russian Academy of Sciences,IAA RAS)分别研制了各自的行星历表。就各个行星历表的发展历程进行概括,对最新版本的3个历表DE438、INPOP19a和EPM2017进行分析,并通过仿真计算比较了月球和行星在太阳质心参考系中的位置和速度的差异,评估了最新历表的相对精度,为中国深空探测和自主历表研制提供技术支撑。结果表明,历表间差异均较小,但月球历表的精度有待提高。
To develop lunar and planetary exploration,Jet Propulsion Laboratory(JPL)in America,French Institute of Astromechanics and Ephemeris,and Institute of Applied Astronomy of Russian Academy of Sciences have developed their own planetary ephemeris.We summarize the development history of each planetary ephemeris,and analyze the latest versions of three ephemeris(DE438,INPOP19a and EPM2017).Through simulation calculation,we compare the differences of positions and velocities of the moon and planets in the solar centroid reference system,and evaluate the relative accuracy of the latest ephemeris,which provides technical support for deep space exploration and development of independent ephemeris in China.The results show that the differences between ephemeris are small,while the accuracy of lunar ephemeris needs to be improved.
