Abstract:

The efficacy of a particular satellite design cannot be guaranteed without first examining the problem of pervasiveness of damping. Two recent contributions in the field of motion stability analysis to the general problem of identifying whether a system is pervasively damped are discussed. If the damping is indeed pervasive, then a corollary to the Thomsom-Tait-Chetaev stability theorem can be used to establish conditions for which the system is asymptotically stable. These results are illustrated in terms of a gravitationally stabilized vehicle that has been augmented by means of constant speed rotors.
