俄罗斯应用天文研究所月球历表研究现状

摘要:
空间探测需要越来越高精度的观测和历表支持。俄罗斯科学院应用天文研究所研发了满足精度要求的月球历表EPM-ERA,它与同期的法国INPOP历表和美国DE历表比较,精度方面有微小差距。分析了进一步提高历表精度的方法。然而EPM-ERA仅仅依赖于法国和美国台站提供的月球激光测距LLR 数据,为了克服这个限制,应用天文研究所在推进俄罗斯西伯利亚阿尔塔伊LLR 地面站的重建任务,以改善LLR 测站分布的几何构型。俄罗斯的月球全球和月球资源探月计划为改进月球历表提供了机会,参与了多次国际深空探测的俄罗斯VLBI网“QUASAR”也将参与这些俄罗斯月球探测计划的精密测轨跟踪。

Current State and Prospects of Lunar Ephemeris in IAA RAS

Abstract:
More accurate observations and ephemerides to support the space programs are required. Currently, lunar ephemerides of adequate accuracy are being developed and maintained by IAA RAS (Institute of Applied Astronomy Russian Academy of Sciences) under the name EPM-ERA. The accuracy of EPM-ERA ephemeris is still worse a little bit than that of competitive French INPOP and American DE ephemerides. The ways to improve the quality of EPM-ERA ephemeris are presented and discussed. However, EPM-ERA ephemeris is based on only measurements kindly provided by American and French LLR observatories. To overcome this problem the project of Russian LLR station was initiated by several organizations including IAA RAS. The proposed location of this station is Siberia, Altai region that promised visible improvement of existing LLR network geometry. Perspectives of the project, current problems and progress are presented and discussed. The impact on improving ephemeris of the Moon is activity of IAA RAS connected with Russian Luna-Glob and Luna-Resource programs. VLBI network "Quasar" is prepared now to observe space vehicles and lunar landers
