Low Thrust Relative Motion Control of Satellite Formations in Deep Space

The problem of placing and controlling a formation of satellites on a Halo orbit is studied. The Earth-Sun circular restricted three body problem is considered. A family of artificial Halo orbits with the same periods, around the L1 and L2 Lagrange points in the Earth-Sun system is found using the pseudo-arc-length continuation method. The orbits are used are reference trajectories for satellites to track. The problem of orbit stability, bounding and controlling the relative motion by means of nonlinear control is addressed.
