Articulated and Flexible Multibody Satellite Dynamics Modelling [PDF]
20th AIAA International Communication Satellite Systems Conference and Exhibit, 2002 This paper is concerned with the deriva- tion of the equations of motion for a maneuvering flex- ible satellite orbiting around the Earth. The structure is assumed to undergo large rigid-body maneuvers and small elastic deformations. The mathematical model is worked out in two levels: in the first one attention is fo- cused on the effects of the rigid ...
