DETERMINING A POSITION BY MEANS OF RFID TAGS
First Claim
1. Method for determining the spatial position and/or orientation of an object (1) marked by means of at least one transponder (2, 2′
- ), wherein the transponder (2, 2′
) receives a query signal emitted by a transmitting device (3) and is excited thereby in order to emit a locating signal, wherein the locating signal is received by means of at least one receiving device (5) and is analyzed by means of an evaluating device (7) to determine the position, characterized in that the transmitting device (3) emits the query signal intermittently, wherein the receiving device (5) receives at least the locating signal emitted by the transponder (2, 2′
) during the transmission pauses of the transmitting device (3) and the evaluating device (7) determines the position therefrom.

Abstract
The invention relates to a method for determining the spatial position and/or orientation of an object (1) marked by means of at least one transponder (2, 2′), wherein the transponder (2, 2′) receives a query signal emitted by a transmitting device (3) and is excited thereby in order to emit a locating signal, wherein the locating signal is received by means of at least one receiving device (5) and is analyzed by means of an evaluating device (7) to determine the position. The object of the present invention is to provide a method that is improved in terms of practicability and above all in terms of precision in determining a position. For this purpose, the transmitting device (3) inventively emits the query signal intermittently, wherein the receiving device (5) receives at least the locating signal emitted by the transponder (2, 2′) during the transmission pauses of the transmitting device (3) and the evaluating device (7) determines the position is therefrom. The invention further relates to a system for carrying out the method.
