Document Type and Number:
WIPO Patent Application WO/2024/062768
Kind Code:
A1
Abstract:
The present invention improves the versatility and convenience of a wireless communication device that performs positioning on the basis of signals received using a plurality of antennas. A first transmission antenna transmits a first transmission signal including one of a request relating to a positioning scheme and a response to the request. A first reception antenna receives a first satellite signal. A second reception antenna receives a first reception signal including either the other of the request and the response, or a beacon signal. A selector selects either of the first satellite signal and the first reception signal and supplies the same as a selected signal. A first quadrature detection unit performs quadrature detection with respect to the selected signal. A processing unit measures a current position on the basis of either the first satellite signal or the beacon signal.
