The system has a three plate combination (1-3) and a two plate combination (60, 61). The total movement combining three rotational movements around three axes called pitch, roll and yaw is retrieved at the level of an upper side of an upper plate (3). The axes of pitch, roll and yaw are two by two orthogonal and cut by a single point (8). The point constitutes center of fictional cardan joint of the system. The three plate combination (1-3) comprises of a lower plate (1), a middle plate (2) and an upper plate (3). The two plate combination (60, 61) comprises of a mounting plate (60) and a movable plate (61). |
