Abstract
In accordance with a first aspect of the present disclosure, a localization device is provided, comprising: an ultra-wideband, UWB, communication unit configured to transmit a localization signal to an external device and to receive a response signal from the external device; an angle of arrival measurement unit configured to measure an angle at which the response signal is received; an orientation sensor configured to sense an orientation of the localization device; and a processing unit configured to determine if an angle at which the localization signal is received by the external device, an orientation of the external device, said orientation of the localization device, and said angle at which the response signal is received meet a predefined relationship. In accordance with a second aspect of the present disclosure, a corresponding method of operating a localization device is conceived.
