EINRICHTUNG ZUM STABILISIEREN EINER ANTENNENPLATTFORM. |
摘要 |
A stabilised platform (1) which is suitable for stabilising the bore-sight of a communications antenna or the like, is provided with pendulous mounting which holds the structure erect. A pair of gyroscopes (20,23) give active control of the attitude of the platform (1), and are coupled to the platform via a gear arrangement (13). When the platform is rotated rapidly by means of a motor (17) (to unravel feed cables or to permit overhead tracking of the antenna) the gyroscopes experience a much lesser degree of movement which is determined by the gearing ratio, such that the gyroscopes are not destabilised. |
