Abstract

PURPOSE:To reduce errors by reflection waves and determine the position of a moving station by providing antennas that can be moved in position or antennas disposed at given intervals to the moving station and at least one of receiving stations disposed in a plurality of given positions, receiving a signal from the moving station by each receiving station and making even thereof.
