Abstract : A preliminary design of the Navy Postgraduate School Mini-Satellite consists of a long cylindrical body and four radial booms and uses the single spin stabilization scheme for its attitude control. Stability conditions between design parameters for simple spinning motions of the satellite in space are investigated by applying Liapunov stability theory and using the natural modes as the admissible functions of internal coordinates. The stability diagram from this study shows that the internal stability conditions due to the flexibility of booms limit the angular velocity range of simple spins while the Maximum Axis Rule limit the minimum lengths of booms. Keywords: Flexural structures; Satellite attitude; Spin stabilization; Satellite booms.
