This paper develops a new Lyapunov-based controller for control of spacecraft flying in formations. Classical orbital elements are used to model the state-space dynamics. Using Gauss's variational equations, a low-thrust, closed-loop feedback controller is developed. It is shown that orbital elements-based controllers will generally perform better on low Erath orbits because the orbital transfer problem associated with the formationkeeping is weakly stabilizeable on geosynchronous and high Earth orbits.
