A procedure for calibrating a sextant is described that requires the use of only two autocollimators, a plane mirror, and a marble surface plate of good quality. The method does not involve the telescope of the sextant except for aligning its optical axis parallel to the plane of the limb. The marble serves as the principal reference plane, while a 180-degree reference angle in a plane parallel to the principal reference plane is defined by the optical axes of the two autocollimators. Calibration of the limb graduation is based on establishing a comparison between the 180-degree reference angle and the sum of the equal angles through which the alidade and the sextant must be turned.
