A method for adjusting the orientation and for compensating interfering torques via solar pressure torques for a satellite moving on an orbit around the earth. The satellite has two solar generators arranged symmetrically on opposite sides of a main body of the satellite. The two solar generators are rotatable independently of one another via servomotors about a first axis of rotation orthogonal to an orbiting plane of the satellite when the position of the satellite is correct. The method comprises the step of: optionally generating solar pressure torques about at least one of three space axes oriented orthogonally with respect to one another, as a result of an adjustment of the solar generators by a targeted rotation about second axes of rotation orthogonal to the first axis of rotation or about the first axis and the second axes of rotation, with respect to a nominal orientation in which the solar generator\s normals to surfaces are precisely aligned in the direction of the sun.

A method for adjusting an orientation of a satellite moving on an orbit around the earth, the orbit having an orbiting plane, and for compensating interfering torques via solar pressure torques for the satellite, said satellite having two solar generators (104, 105), having active surfaces, arranged symmetrically on opposite sides of a main body of said satellite, said two solar generators being rotatable independently of one another via servomotors about a first axis (109, 110) of rotation coinciding with a pitch axis (YF) of a satellite-fixed system of axes (XF, YF, ZF) which pitch axis is orthogonal to the orbiting plane of the satellite for a nominal orientation of the satellite, the method comprising the steps of: nominally orienting (a0, b0) the solar generators by rotation about at least one of said first axis of rotation (a0) and a second axes of rotation such that normals (XPN, XPS) to their active surfaces align precisely in a direction of a sun; adjusting the solar generators via a targeted rotation (eN, eS, gN, gS) about either said second axes (301, 302) of rotation b0, or said first and second axes of rotation, so as to selectively generate solar pressure torques (T0X, T0Y, TZ) about at least one of three space axes (X0, Y0, Z0) oriented orthogonally with respect to one another forming a coordinate system in which the first space axis (X0) is in a plane of incidence of the sunlight.
