EQUILIBRIA ASSOCIATED WITH THE ATTITUDE DYNAMICS OF A RIGID BODY IN KEPLERIAN MOTION Conference Paper

We show that the use of Classical Rodrigues Parameters for the attitude motion of the rigid body subject to gravity-gradient torques enables us to characterize the rotational motion about its mass center. The stability of oscillations is investigated using inertia as a parameter and it is shown that large oscillations are induced due to the energy exchange between the pitching and roll-yaw motion of the rigid body. Furthermore, the effect of moments of inertia on the attitude motion is studied under the framework of a higher order approximation of the gravity-gradient potential.
