This research proposes a relative position and attitude control method using magnetic force with dipole magnets for formation-flighting spacecrafts without reaction wheels. This technology can be widely applied to re-configurable space structures that architect or/ re-structure themselves by assembling basic structural units. One remarkable benefit is that this control method can extend mission term in comparison to conventional control methods with magnetic force because spacecrafts never require any types of fuel for position controls or unloadings. This paper focuses on current control of dipoles which produce strong nonlinear magnetic forces and suggested a way of linearization of a nonlinear system for control. Also feasibility of this method and controllability are investigated, then the series of attitude control simulation are shown, and the next step for developing this technology will be discussed in the following chapter.
