Abstract : This paper addresses orbital perturbations in the two-body problem of an earth-orbiting solar sail undergoing free coning motion in a circular orbit. The coning motion controls both the magnitude and direction of the solar radiation pressure force. The equations of motion are expanded from the Language planetary equations in their acceleration component form and are solved assuming small changes in the orbital elements over the period of one orbit. Resonances are observed between the mean motion of the sail and its precession rate. The one-to-one resonance case is examined and numerical methods are employed to verify the analytic results for the circular orbit case. (Author)
