Popis:	Analytical and numerical methods are used to investigate the dynamics of a rotating two-body spacecraft system perturbed by first order gravity-gradient torques. The first order linear equations contain periodic coefficients with frequency at twice the system spin rate and the in-plane equations are forced at the same frequency. The amplitudes of all nonresonant steady-state motions are small. Conditions resulting in gravity-gradi ent induced resonances are examined analytically for special cases. The effect of damping on resonance is considered numerically.
