METHOD OF SEMI-PASSIVE THREE-AXIS STABILISATION OF DYNAMICALLY SYMMETRIC ARTIFICIAL EARTH SATELLITE Russian patent published in 2008 - IPC B64G1/38 B64G1/32 B64G1/24 

FIELD: transport.

SUBSTANCE: invention relates to space engineering and can be used for stabilisation of artificial Earth satellites (AES) using a geomagnetic field. In compliance with the proposed method, a double electrically static layer is distributed on over a part of the satellite surface. Because of the AES orbital flight the said layer interacts with the Earth magnetic field to generate a control moment of Lorentz forces that can, in fact, exceeds the moment of gravitation acting on larger AES with a dynamic symmetry approximating to a complete symmetry, or acting on a gravitation-oriented AES. To control orientation of AES with an axial dynamic symmetry, the magnitude and direction of the double layer dipole moment vector are changed to comply with projections of the AES centre of mass velocities and geomagnetic induction vector onto the axes of the orbital coordinate system. The derive law of varying the said vector allows stabilising the AES position nearby the point of equilibrium whereat the AES dynamic symmetry axis is aligned with the local vertical. Given the damping, this AES is stable under effects of gravitational and the like minor disturbances.

EFFECT: expanded range of application of the said AES orientation control method.
