ABSTRACT:
A satellite mechanism is provided for tilting a directional device such as an earth sensor, telescope, antenna, reaction wheel, etc. through a small angle using flexural supports which provide rigidity in all directions. The tilting mechanism is flexurally supported (semi-fixed) on two points and moved (pivoted) through a small arc at a driven point by an eccentric drive. The flexurally supported points comprise a diaphragm whose periphery is clamped to a supporting structure while one side of a flexural pivot is attached at the center and the other side of the flexural pivot is attached to the earth sensor or pivoted element. The driven point has a similar diaphragm whose periphery is attached eccentrically to an harmonic drive motor. Accordingly, the directional device may be driven through a small angle without moving the entire satellite.
