Automatic inertial navigation system calibration method, and apparatus and system thereof

The invention relates to an automatic inertial navigation system calibration method, and an apparatus and a system thereof. The method comprises the following steps: adjusting an initial rotating table plane to be completely horizontal; carrying out power-on initialization on the system; pressing a connecting key to connect a product to be calibrated; and pressing a calibration key after successful connection to calibrate the product to be calibrated. The method, the apparatus and the system have the advantages of calibration precision improvement, operation mode optimization and calibration rate increase.
