N2 - Proximity operations at multiple asteroid systems involve higher degrees of complexity due to added perturbations. In this paper, we adapt a Multiple Sliding Surface Guidance (MSSG) algorithm developed for close proximity operations at a single asteroid, and extend its applicability to binary asteroid systems. The advantage of using MSSG is that no trajectory is needed to be computed offine as the commands use the spacecraft accelerations directly. We show simulations of a two-sphere binary systems where the velocity cost and associated transfer times show to be minimal.
