Asset tracking system and method

Abstract

According to an embodiment of the present invention: in order to track an accurate location of an asset, an asset location, which is a location of an asset terminal installed in the asset to be tracked, is measured; a relative location of the asset terminal, which is based on a reference terminal, is measured through communication between the reference terminal and the asset terminal; and the asset location is corrected using the relative location. Based on this, the present invention minimizes a measurement error of an asset location, compared to a scheme of measuring an asset location by using only GPS communication.
