A new orbit for the global observation of Phobos, the first satellite of Mars, is presented in this paper. It is shown that the global survey of Phobos with both the high resolution of about 1m and various solar phase angles can be made during the period of one Martian year from this new orbit. That orbit is named here as “Phobos-Rendezvous Orbit.” The gravity from Phobos plays a significant role for the global observation with almost no fuel. This orbit, however, is adjacent to an instable one. Increment of the inclination of the rendezvous orbit puts the orbit into the instable region. Simulation of the stabilization maneuvers indicates that the Phobos-Rendezvous Orbit can be maintained with small amount of fuel.
