摘要

目前,有许多机器人和载人探月项目正在开发中。为此目的,各空间机构特别注意为即将进行的空间任务提供协调和时间支持。特别是,俄罗斯航天局计划将GLONASS导航系统扩展到月球轨道。导航月心系统的建立意味着月球物理振动(PLM)数值理论的重大发展和完善,该理论定义了月球惯性轴相对于平均黄道的位置。在缺乏可靠的PLM理论的情况下,月球空间任务的坐标和时间支持并不具有所需的精度。本文主要研究了PLM理论的构建及其可靠性分析。介绍了建立PLM理论和计算月球轨道参数的算法。利用DE421星历建立了数值PLM理论。在与Rambaux, Williams (Rambaux, N., et al., Rambaux, N., et al.)的相应理论进行比较的基础上,通过分析其残差来评估PLM理论的准确性。

Correction: Analysis of dynamic ephemeris and physical libration of the Moon in order to create a lunar navigational system
Currently, there are a number of projects on robotic and manned exploration of the Moon are being developed. With this purpose, the space agencies pay particular attention to providing coordinate and time support for the upcoming space missions. In particular, Roskosmos is planning to extend GLONASS navigational system to the lunar orbit. Construction of navigational selenocentric systems implies significant development and refinement of the physical libration of the Moon (PLM) numerical theory that defines position of the lunar axes of inertia in relation to the mean ecliptic. In the absence of reliable PLM theory coordinate and time support for the lunar space missions does not have the required accuracy. The present work is mainly concerned with the construction of PLM theory and analysis of its reliability. The authors’ algorithm of building PLM theory and calculating lunar orbit parameters is described. As a result, a numerical PLM theory is developed using DE421 ephemeris. The accuracy of the PLM theory has been assessed by analyzing its residual differences on the basis of comparison with corresponding theories by Rambaux, Williams (Rambaux, N., et al., Rambaux, N., et al.).
