It is mission critical to avoid collisions between satellites as they moving in space. We present a method based on the barrier theory of differential game that may consider one satellite as a pursuer, the other as evader. According to optimal control theory, Hamiltonian function with the state inequality constraints of the min distance between adjacent satellites is investigated, and then obtaining optimal control. Finally the barrier trace is achieved according to barrier theory.
