“…Finally, among more exploratory projects, LISA-like configurations for interplanetary laser distance measurements between telluric planets (Earth, Mars and Venus) have been proposed as a way to gain accuracy in planetary ephemerides and sensitivity to general relativity violations such as the secular variations of the gravitational constant (Smith et al 2018). Despite the technical challenges of such project (Bills and Skillman 2022;Bills and Gorski 2022), the outcome of these measurements would indeed impact the global accuracy of the ephemerides, improve significantly the Bepi-Colombo results but also allow for better constraints on the distribution of mass in the solar system.…”

We describe here how planetary ephemerides are built in the framework of General Relativity and how they can be used to test alternative theories. We focus on the definition of the reference frame (space and time) in which the planetary ephemeris is described, the equations of motion that govern the orbits of solar system bodies and electromagnetic waves. After a review on the existing planetary and lunar ephemerides, we summarize the results obtained considering full modifications of the ephemeris framework with direct comparisons with the observations of planetary systems, with a specific attention for the PPN formalism. We then discuss other formalisms such as Einstein-dilaton theories, the massless graviton and MOND. The paper finally concludes on some comments and recommendations regarding misinterpreted measurements of the advance of perihelia.

This study is done in the context of the project titled Interplanetary Laser Tri-lateration Network (ILTN) proposed by [5] and investigated more in details by [1] and [2]. The original idea was to propose interplanetary measurements (in this case between Venus, Mars and the earth) as a way to measure the solar system expansion. But some recent interests on the measurement of asteroid masses and more generally the study of the mass distribution in the outer solar system appear with the ILTN. In this work, we are investigating how different possible configurations of interplanetary measurements of distances can be introduced in planetary ephemeris construction and how they improve our knowledge of planet orbits and other related parameters.
