Abstract
The motion of a dual spin satellite in circular orbit is studied to determine the effect of gravitational torques and damping when the spin vector is approximately normal to the orbit plane. Stability results are assessed by the Floquet method for selected cases to show that gravitational torques are important when spin rates are low. Solutions are obtained analytically for high spin cases using the method of averaging to demonstrate the effect of gravitational torque and damping on both rotor and despun platform. For the high spin cases, stability criteria are identical with criteria previously derived for a freely spinning untorqued dual spin satellite.
