An Expected LLR Station in Russia and its Impact on the Lunar Ephemeris Accuracy

Transactions of IAA RAS, issue 35, 74–79 (2015)

Keywords: Lunar ephemeris, LLR observations, mathematical simulation, optimal geographical position.

Abstract

A possible impact on the accuracy of the lunar ephemeris parameters made by a new lunar laser which is being installed on the 3.12 m telescope at Altay station (Russia), is under consideration in this article. The main criterion choosing observatories to install LLR equipment is their location close to the equator and availability of all required infrastructure there. The geographical position of possible LLR stations is evaluated using a mathematical simulation based on the latest version of lunar ephemeris EPM-ERA 2014 which has been developed in IAA RAS. It is supposed that the observational program of the Russian LLR is analogous to the programs of actively working LLR stations Apache (USA) and Cerga (France). The obtained lunar ephemeris parameters can become more accurate after running 7 years of LLR observations using an optimal program at Altay stations. The expected accuracy growth in this case is from 16 % to 20 % for those stations which are located in an optimal geographical area

AB  - A possible impact on the accuracy of the lunar ephemeris parameters
made by a new lunar laser which is being installed on the 3.12 m
telescope at Altay station (Russia), is under consideration in this
article. The main criterion choosing observatories to install LLR
equipment is their location close to the equator and availability of
all required infrastructure there. The geographical position of
possible LLR stations is evaluated using a mathematical simulation
based on the latest version of lunar ephemeris EPM-ERA 2014 which has
been developed in IAA RAS. It is supposed that the observational
program of the Russian LLR is analogous to the programs of actively
working LLR stations Apache (USA) and Cerga (France). The obtained
lunar ephemeris parameters can become more accurate after running 7
years of LLR observations using an optimal program at Altay stations.
The expected accuracy growth in this case is from 16 % to 20 % for
those stations which are located in an optimal geographical area
