Abstract: The present device comprises in combination a first element consisting of a base plate (8), at least a second element having a substantially cylindrical shape (9), of which one of its faces is in an inclined plane, at least a third element having a substantially cylindrical shape (10) of which one of its faces is an inclined plane, a fourth element consisting of a support plate (11) for the useful load, motor means for actuating at least one of those elements with respect to at least one of the other elements, means for coupling these elements between each other allowing a relative rotation of said elements, and means capable of preventing the rotation of one of said elements with respect to another of said elements. The device can be used for the orientation, positioning or displacement of a useful load, particularly to the pointing of solar panels, satellite antennae, telescopes, etc.
