Constraining the Mass of the Graviton with the Planetary Ephemeris INPOP. [PDF]
Physical Review Letters, 2019 We use the planetary ephemeris INPOP17b to constrain the existence of a Yukawa suppression to the Newtonian potential, generically associated with the graviton's mass.

CALCULATION AND MAPPING OF TIDAL LUNAR IMPACTS ON THE EARTH SPHEROID
InterCarto. InterGIS, 2017 The major method used in this study is processing of data arrays in order to obtain statistical data. Statistical methods of research use the parameter of frequency to characterize the recurrence of events in time and space.

Astrometry of mutual approximations between natural satellites. Application to the Galilean moons [PDF]
, 2016 Typically we can deliver astrometric positions of natural satellites with errors in the 50-150 mas range. Apparent distances from mutual phenomena, have much smaller errors, less than 10 mas. However, this method can only be applied during the equinox of

Updated Ephemeris and Evidence for a Period Change in the Eclipsing Novalike Variable 1RXS J064434.5+334451 [PDF]
arXiv, 2021 We report seven new eclipse timings for the novalike variable 1RXS J064434.5+334451. An analysis of our data, along with all previously available timings (36 published and 16 unpublished), yields a best-fitting linear ephemeris of BJD$_\mathrm{ecl} = 2,453,403.7611(2) + 0.269~374~43(2)~\mathrm{E}$.
arxiv
Metrology and Measurement Systems, 2020 The possibilities to improve values of the satellite orbit elements by employing the pseudo-ranges and differences of carrier phase frequencies measured at many reference GPS stations are analysed. An improvement of orbit ephemeris is achieved by solving
