| Abstract | 美国DE系列、法国INPOP系列和俄罗斯EPM系列数值星历表是目前公认处于世界领先的3种行星数值历表。计算100 a(1960—2060年)间,3种数值历表中大行星(包含月球)相对地球和相对太阳系质心的位置坐标差分最大值及均方根。结果表明,3种历表对太阳系质心的测量存在百米到公里量级的偏差,EPM2017与其他两个相差较大。考虑相对地心的位置,水星和金星的历表精度在百米量级;火星的历表精度在百米到公里量级;木星和土星的历表精度在几公里到几十公里量级;天王星和海王星的历表精度在几百公里到几千公里量级;月球历表的精度在分米到米量级,其径向距离精度在分米量级。此结果为地月空间科学实验及深空探测应用提供了支持和依据。 |
| Other Abstract | The US DE series,the French INPOP series,and the Russian EPM series ephemerides are three types of the world's leading numerical planetary ephemerides.In this paper,the maximum values and the root-mean-squares of the positions of the major planets(including moon)relative to the earth and the barycenter of the solar system in the three numerical ephemerides during one hundred years(1960-2060)are calculated.The results show that the deviation levels of the measurements about the solar system barycenter range from hundred meters to kilometers,and the differences between EPM2017 and the other two are large.Taking the earth as the reference point,the accuracies for Mercury and Venus are at one hundred meter level.The accuracy of Mars ranges from hundred meters to kilometers.The accuracies for Jupiter and Saturn range from several kilometers to tens of kilometers.The accuracies for Uranus and Neptune range from several hundred kilometers to thousands of kilometers.The accuracy of Lunar ephemeris ranges from decimeter to meter,and its radial distance accuracy is at the decimeter level.These results provide support and basis for the cislunar space science experiment and deep space exploration application. |
