About the paper Full textAbstract
The modern Lunar Ephemerides DE (USA), INPOP (France), EPM-ERA (Russia) have been obtained through the comparison of dynamical models of the Moon orbital and rotational motion with modern highly precise lunar laser observations (LLR) from 1969 to the present time. The main purpose of this paper is to evaluate the impact of adding new types of observations on the accuracy of lunar ephemerides. These types are VLBI and radio ranging observations of a lunar lander equipped with a transponder like the one in the Chinese space project Chang’E-3 with the Yutu rover placed at the Moon’s surface [1]. The evaluation was made through the mathematical simulation method for various radio telescopes networks and measurement accuracies. Mathematical models were created by the ERA system developed in the IAA RAS [2]. The results show that VLBI observations processing together with LLR can considerably improve the accuracy of some lunar parameters.

AB - The modern Lunar Ephemerides DE (USA), INPOP (France),
EPM-ERA (Russia) have been obtained through the comparison of
dynamical models of the Moon orbital and rotational motion with
modern highly precise lunar laser observations (LLR) from 1969 to the
present time. The main purpose of this paper is to evaluate the
impact of adding new types of observations on the accuracy of lunar
ephemerides. These types are VLBI and radio ranging observations of a
lunar lander equipped with a transponder like the one in the Chinese
space project Chang’E-3 with the Yutu rover placed at the Moon’s
surface [1]. The evaluation was made through the mathematical
simulation method for various radio telescopes networks and
measurement accuracies. Mathematical models were created by the ERA
system developed in the IAA RAS [2]. The results show that VLBI
observations processing together with LLR can considerably improve
the accuracy of some lunar parameters.
