In the present work the results of the investigation of the unguided artificial objects which belong nowadays to Space Debris, have been considered.
The experience of the analysis of these results has proved that such objects may serve indicators in basic perturbating moment study. One of the methods of perturbation reveling is investigation of the objects orientation changes in space.
The determined secular precession makes it possible to establish the origin of the basic perturbating forces. The obtained results show that this is mainly the Moon that influences the dynamics of the heavy satellites rotation. The season change of the period of the satellite rotation throughout the year may be caused by the interaction of two perturbating components: magnetic moment and the Sun radiation pressure.
The major methods of investigation have been worked out in Uzhgorod University.
