Simulations of Quasi-Satellite Orbits Around Phobos

In this work, quasi-synchronous orbits around Phobos are studied from a preliminary mission design point of view. Addressed issues include stability of the orbits, possible choices of specific suitable orbits, and their impact on the design of a mission to Phobos (eclipses, observation conditions, etc.). An exploration of the phase space is performed to assess the precision requirements on the initial conditions of the spacecraft state vector for insertion into these orbits. The possibility of using an orbit outside the orbital plane of Phobos around Mars is also explored.
