Abstract
In order to provide a method for locating moving objects that will allow high precision in position determination and thus largely eliminate sorting errors, and also to provide a device suitable for executing the method, it is envisaged that on at least one defined location within the reading range of an interrogator () arranged in a stationary position, an interference pulse, which influences a response signal transmitted by a transponder () carried by a moving object () in response to a signal transmitted by the interrogator (), is exerted on the object (), and a position of the object () is determined in dependence on a time when the influence of the response signal occurred.
