Zusammenfassung:	Apparatus for comparing heading angle information provided by a directional gyro with that provided by a magnetic heading device (compass), and providing a bipolar d.c. error signal corresponding to the long time average difference therebetween. The error signal may be used to drive an indicating device or to torque the gyro until the heading error is washed out.
