Systems and methods for a lightweight north-finder (200). A method of using a north-finder includes a tube (102) configured to fire munitions secured to a base (106). A north-finder is coupled to a tube in order to determine an azimuth and elevation. The north-finder is rotated ninety degrees about an axis (206) 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 (302), an accelerometer (304), and an inertial measurement unit (306), wherein, when the north-finder is rotated ninety degrees about an axis parallel to the tube, azimuth and elevation values are confirmed.
