We consider the problem of stabilization of a rotatory movement of a satellite with one or two gyrodins. Present results touch upon the stability of dynamical systems with respect to part of the variables. The controls are obtained to which the fixed solutions of the system rigid body-gyrodins correspond. The solutions are positions of relative equilibriums and uniform rotations of a satellite. The cases of a controllability of a system are chosen on a linear approximation irf a neighbourhood of the fixed motions derived. In this case we construct the controls to provide stabilization of angular velocity and stabilization of uniform rotation of a satellite.
