Abstract
The invention relates to a directional gyro having two mutually perpendicularly arranged gimbals. The first or outer gimbal is fastened to a frame by means of a trunnion having a perpendicular axis. This axis is provided with an angle pickup to determine the course angle. The second or inner gimbal is provided with a gyro motor comprising a stator and a rotor, with the rotor axis being held in a horizontal orientation by means of a verticality device. According to the invention, the verticality device comprises an element which displaces the center of gravity of the inner gimbal and is attached, for example, to this inner gimbal, and an element which damps the rotary movement about one of the gimbal axis and which is formed, for example, of a ball bearing subject to a defined friction or of a slip brush.
