Dynamic calibration system and method for inertial orbit measurement instrument and application of dynamic calibration system and method

The invention discloses a dynamic calibration system and method for an inertial orbit measurement instrument and application of the dynamic calibration system, and the dynamic calibration system is based on the combination of a double-speed sensor and a vehicle-mounted antenna array, and comprises a track, a track gauge sensor, an inertial sensor and a differential base station, the center position of each ground antenna of the vehicle-mounted antenna array is provided with a corresponding engineering coordinate system coordinate; the data of the same ground antenna and the data of at least two differential base stations are solved; the track adopts a speed sensor for speed measurement and is matched with a track gauge sensor for course angle deviation measurement; the speed change and the angle change are used for acceleration and angular speed calibration of the inertial sensor; and the differential base station realizes wireless communication with the vehicle-mounted antenna array through a wireless commun
