The main purpose is to determine all equilibria positions for our spacecraft in the case when internal angular momentum of the gyrostat satellite is collinear to its principal axis of inertia, when the gyrostatic moment vector lies in one of the satellite’s principal central plane of inertia and for a general position where the gyrostatic moment doesn’t coincide with any of the principal axis of inertia.engVeículo espacialDinâmica girostáticamaster thesis
