The method includes the steps of determining a working state of the Inertial Navigation System based on a current positioning parameter of the moving object, a navigation map-based reference positioning parameter and a GPS-based reference positioning parameter, and replacing an initial parameter of the Inertial Navigation System with the GPS-based reference positioning parameter and resetting the Inertial Navigation System to an initial state if the Inertial Navigation System is determined to be in an abnormal working state.",
