<p>The proposed triaxial gyroscopic stabiliser for a movie or television camera comprises a movie or television camera (1) in a cardan suspension unit, two three-stage gyroscopes (11, 17), control linkages for adjusting course (10), banking (9) and pitch (8), booster-converters (13, 19, 21), a set of accelerometers (22, 23, 24), a pitch angle sensor (25), an integrator (35), a system shut-off unit (40), a memory unit (32), low-frequency filters (26, 30), two computing units (31, 38), a summator, and course and pitch control levers (36 and 33 respectively). The cardan suspension unit comprises an external frame (6), a middle frame (4) and a platform; the outer frame takes the form of a half-fork bracket with an axis of rotation (7) aligned along the course axis; The middle frame (4) takes the form of a fork bracket with an axis of rotation (5) aligned along the banking axis; and the platform has an axis of rotation aligned along the axis of pitch. The first of the two three-stage gyroscopes is mounted on the platform, while the second is mounted on the middle frame.</p> |
