An analysis is made of the rotational motion in circular orbit of a satellite gyrostat with a permanent magnet under the effect of gravitational and magnetic moments in the earth's magnetic field. This motion is described by a system of sixth-order ordinary differential equations with periodic coefficients. Analytical and numerical methods are used to obtain symmetric periodic solutions to this system which are close to periodic solutions of a corresponding second-order degenerate system. On near-polar orbits, the motions described by such solutions can be used to realize three-axis magnetic attitude control.
