This paper considers adaptive relative attitude tracking control of two spacecraft formulated in SO(3) using line-of-sight measurements. The objective is to control the attitudes of individual spacecraft with unknown moment of inertia so as to track a specified time-varying relative attitude trajectory. We propose an estimation scheme for the moment of inertia. Proposed control torques and estimation schemes are obtained in terms of line-of-sight measurements. The trajectories of the resulting closed loop system are shown to be asymptotically tracking the desired time-varying trajectories.
