First Claim
1. A calibration method, comprising:
- providing a mounting fixture including a tray coupled to a frame, and an alignment measurement sensor removably coupled to the tray;
determining an angular orientation of the tray using the alignment measurement sensor removably coupled to the tray in a first position;
moving the alignment measurement sensor to a second position on the tray that is rotated from the first position;
determining the angular orientation of the tray using the alignment measurement sensor at the second position;
calculating an axis misalignment for at least two of a pitch axis, a roll axis, or a yaw axis of the alignment measurement sensor to determine one or more misalignment factors; and
applying the one or more misalignment factors to correct for misalignment of the alignment measurement sensor.

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.

19. A computer program product, comprising:
a non-transitory computer readable medium having instructions stored thereon executable by a processor to perform a calibration method, comprising; determining an angular orientation of a tray coupled to a frame based on data from a frame alignment measurement sensor removably coupled to the tray in a first position and orientation; determining the angular orientation of the tray based on data from the alignment measurement sensor after being moved to a second position and orientation on the tray that is spaced apart and rotated from the first position and orientation; calculating an axis misalignment for at least two of a pitch axis, a roll axis, or a yaw axis of the alignment measurement sensor to determine one or more misalignment factors; and applying the one or more misalignment factors to output angles of the frame alignment measurement sensor to correct for misalignment of the frame alignment measurement sensor.
