Research on calibration technology of weapon equipment transfer alignment system

The advantages of three degrees of freedom attitude measurement technology such as high measurement accuracy, long measurement distance, and large measurement range make it widely used in aerospace weapons. This article briefly describes the basic principles of the transfer alignment system in weapons and equipment, introduces the basic principles and system composition of the on-site calibration device for the reference light transfer system in response to the on-site testing and calibration requirements of the transfer alignment system in weapons and equipment, and analyzes the preliminary measurement results.
