An Integrated Calibration Method of the Inertial Group on the Missile without Opening Box

In order to shorten the calibration time and simplify the calibration process, the missile and launch box are jointly involved in the calibration, so as to complete the calibration of the inertial group on the missile without opening box. However, due to the large volume and mass of the missile, the...
