Assessment of Phobos gravity field determination from both near polar and near equatorial orbital flyby data

Andert, T.; Li, F.; Yan, J. G. +5 more

The C₂₀ and C₂₂ coefficients of the Phobos gravity field are key parameters to constrain the internal structure of the Martian moon, but reliable observed values of these parameters are still missing. In this paper, we demonstrate, through a combination of forward and inverse modelling of simulated Doppler spacecraft tracking…
