  This study is done in the context of the project titled Interplanetary Laser
Tri-lateration Network (ILTN) proposed by \cite{2018P&SS..153..127S} and
investigated more in details by \cite{2022P&SS..21405415B} and
\cite{2022P&SS..21505423B}. 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.
