Systems and methods for a lightweight north-finder. A method of using a north-finder includes a tube configured to fire munitions secured to a base in preparation of firing operations. A north-finder coupled to a tube in order to determine an azimuth and elevation. The north-finder is rotated ninety degrees about an axis parallel to the tube in order to confirm the determined azimuth and elevation. The determined azimuth and elevation is displayed to a user. A system of using a north-finder includes a tube configured to fire munitions secured to a base. A north-finder mount coupled to the tube having a north-finder is configured to determine an azimuth and elevation. The north-finder includes a ring laser gyro, an accelerometer, and an inertial measurement unit, wherein, when the north-finder is rotated ninety degrees about an axis parallel to the tube, azimuth and elevation values are confirmed.
