description	A simplified gyrocompass including a primary reference gyroscopic wheel which is supported in a two axis gimbal system, with an inertia wheel which serves as a primary directional stabilization means. Included is two axis torquing means which replaces conventional high response positional control motors. A third stabilizational gimbal which is normally required is eliminated and replaced by a signal modifier sensitive to cross tilt displacement. A simplified displacement sensing and torquing system is also provided for the primary reference gyro.
