Abstract : The patent relates to a gyroscopically stabilized platform provided with servo controls to eliminate gross pitch and roll motions of a ship on which the platform is mounted. The platform is fitted with gyroscopes which generate a voltage signal when the platform moves from its stabilized position. The voltage signal so produced is processed electronically in a control box wherefrom a signal is sent to servo valves which change hydraulic flow in an electro-hydraulic system of the platform. This change in hydraulic flow is such as to energize a group of actuators which command the platform back to the commanded stabilized position.
