We present here the new INPOP lunar ephemeris, INPOP17a. This ephemeris is obtained through the numerical integration of the equations of motion and of rotation of the Moon, fitted over 48 yr of lunar laser ranging (LLR) data. We also include the 2 yr of infrared LLR data acquired at the Grasse station between 2015 and 2017. Tests of the universality of free-fall are performed. We find no violation of the principle of equivalence at the (−3.8 ± 7.1) × 10^−14 level. A new interpretation in the… 

Role of lunar laser ranging in realization of terrestrial, lunar, and ephemeris reference frames

Three possible applications of lunar laser ranging to space geodesy are studied. First, the determination of daily Earth orientation parameters (UT0 and variation of latitude) is rarely used nowadays

Constraining the Mass of the Graviton with the Planetary Ephemeris INPOP.

The planetary ephemeris INPOP17b is used to constrain the existence of a Yukawa suppression to the Newtonian potential, generically associated with the graviton's mass, and to defend that constraints on alternative theories of gravity obtained from postfit residuals may be generically overestimated.

Estimation of the lunar free libration modes based on the recent ephemerides

The accuracy of lunar laser ranging (LLR) experiment has already increased to about 1 cm in recent years. When the LLR data joined to the lunar dynamical model updated from DE430, three independent

Benefit of New High-Precision LLR Data for the Determination of Relativistic Parameters

Since 1969, Lunar Laser Ranging (LLR) data have been collected by various observatories and analysed by different analysis groups. In the recent years, observations with bigger telescopes (APOLLO)

Influence of the layered Moon and Earth’s orientation on lunar rotation

One of the most efficient ways to probe the lunar inner structure at present is through the study of its rotation. Range and range rate (Doppler) data between the Chang’E-3 lander and station on the


The dynamical model of the orbital-rotational motion of the Moon, used in numerically integrated lunar ephemeris, accounts for tidal dissipation. However, it does not explain some long-term

Lunar Laser Ranging: a tool for general relativity, lunar geophysics and Earth science

Only a few sites on Earth are technically equipped to carry out Lunar Laser Ranging (LLR) to retroreflector arrays on the surface of the Moon. Despite the weak signal, they have successfully provided

Comparison and analysis on lunar rotation with lunar gravity field models

Understanding the structure of and dynamic processes in the deep interior of planets is crucial for understanding their origin and evolution. An effective way to constrain them is through observation



The INPOP10a planetary ephemeris and its applications in fundamental physics

Compared to the previous INPOP versions, the INPOP10a planetary and lunar ephemeris has several improvements. For the planets of our Solar System, no big change was brought in the dynamics but

Optimizing the observation schedule for tests of gravity in lunar laser ranging and similar experiments

A worth function is constructed for any fitted parameter of the lunar laser ranging (LLR) model. It quantifies the reduction in the formal noise uncertainty of the parameter's estimated value which

Detection of the lunar body tide by the Lunar Orbiter Laser Altimeter

This work reliably detects the topographic tidal signal and estimates the associated Love number h2 to be 0.0371 ± 0.0033, which is consistent with but lower than recent results from lunar laser ranging.
