ABSTRACT:
In a stabilisation system a platform is stabilised about two perpendicular axes by means of a gyro-controlled servo system. The vertical gyro being used in the stabilisation system is cardanic suspended in a gyro housing mounted on said platform. In a first step the spin axis of the vertical gyro is brought, to some extent, from a random orientation to a position vertical with respect to the earth surface by means of two synchro transmitters coupled to the gyro, first control circuits connected to each of these synchro transmitters, and two torque motors, and in a second step the vertical gyro is held in said vertical position by means of two accelerometers mounted on the platform to be stabilised, second control circuits connected to each of these accelerometers, and the abovementioned torque motors.
