1. A method for measuring a position, performed by a ground assembly (GA) for alignment between the GA and a vehicle assembly (VA), the method comprising:
detecting, by a controller, low frequency (LF) signals transmitted by the VA through LF receive antennas of the GA;
calculating, by the controller, a position of a vehicle based on the LF signals;
receiving, by the controller, information regarding a position of the vehicle estimated by the VA;
calculating, by the controller, an acceleration flag by comparing the position of the vehicle calculated based on the LF signals with the position of the vehicle estimated by the VA; and
transmitting, by the controller, information regarding the position of the vehicle calculated based on the LF signals and the acceleration flag to the VA.
