<p>The system provides positioning of a pointing device about an axis (Z). The mechanism includes two motors (M1 & M2) and three reducing gears (R1, R2, R3), each reducer providing an input stage and an output stage turning about a common axis. The motors and reducers rectify any error in the angle of aim. The system provides positioning of a pointing device about an axis (Z), such that the space containing a point (O) is fixed with respect to a base (E). The mechanism includes two motors (M1 & M2) and three reducing gears (R1, R2, R3), each reducer providing an input stage and an output stage turning about a common axis. The second reducer is mounted on the opposite side of the plane passing through the axis (X1) and orthogonal to the axis (Y1) with respect to the first motor. The motors and reducers are organised in order to rectify any error in the angle of aim introduced by the interferences of the commands for the inclination along the conjugate angles (X1 & Y1) in space.</p> |
