Orbits of the Martian satellites from ESAPHO and ESADE theories
Abstract
The semi-analytical theories ESAPHO and ESADE for the orbital motions of the Martian satellites have been fitted to a large collection of observations including earth-based observations and spacecraft observations from Mariner 9, Viking 1 and 2 and Phobos 2. The influences of various subsets of observations and of the weights assigned to them have been analyzed. The contribution of the perturbations by Phobos' figure has been studied. An interesting agreement of the perturbations computed from Borderies and Yoder's values of inertial parameters with the observations has been obtained.
