ABSTRACT:
In a stabilized gyrocompass having meridian seeking gyroscopic means and slaved horizontal gryoscopic means disposed upon a common platform, a signal representative of the angle which develops between the meridian seeking gyro and the platform in response to the dynamic effects of the vehicle is generated. The generated angle is proportional to the northerly inertial velocity term and is used to control the platform in azimuth, thereby providing a dynamically correct stabilized gyrocompass without the use of accelerometers or gravity sensors which are conventional in the art.
