Kovalevskaya top and attitude dynamics of magnetized satellites in equatorial orbits

The article gives a visual illustration of the dynamics of a heavy rigid body around a fixed point in the case of S.V. Kovalevskaya, which arises in the framework of applied problems of space flight. The motion of a rigid body in the case of S.V. Kovalevskaya (the Kovalevskaya top) is equivalent to the dynamics of the attitude of a magnetized satellite around its centre of mass during orbital motion along equatorial circular orbits. The perturbed motion of the magnetized satellite is considered at small deviations from the conditions of the Kovalevskay top, including a small dynamic asymmetry of the satellite, as well as small variations in the magnitude of the external magnetic moment due to weak ellipticity or non-equatoriality of the orbits.
