Abstract
A calibration method comprises providing a mounting fixture including a tray coupled to a frame, and an alignment measurement sensor removably coupled to the tray. An angular orientation of the tray is determined using the alignment measurement sensor removably coupled to the tray in a first position. The alignment measurement sensor is then moved to a second position on the tray that is rotated from the first position, and the angular orientation of the tray is determined using the alignment measurement sensor at the second position. An axis misalignment for at least two of a pitch axis, a roll axis, or a yaw axis of the alignment measurement sensor is then calculated to determine one or more misalignment factors. The one or more misalignment factors are then applied to correct for misalignment of the alignment measurement sensor.
