Inertial guidance measuring equipment and its calibration

This paper explains the functions and varieties of inertial guidance measuring equipment, and gives information about its typical structures and the concept of basic accuracy index. This paper also describes that the development trend of the equipment is the general arrangement will be developed toward horizontal one; the shafting structure toward active magnetic suspension type; the structure toward the spherical shell which is made of composite material; the power transmission toward rolling ring direction and the indexing elements will be replaced by high accuracy induction synchronizer, One example of calibration technology is illustrated and its development direction is pointed out:continuously developing calibration accuracy; carring out dynamic calibration and improving the adaptability of measuring equipment to 3-D spacial position. In addition, systematic management, standard terms and data processing, and good cooperation of design with calibration must be guaranteed.
