    摘要： A system and a method for position determination by impulse radio using a first transceiver having a first clock providing a first reference signal and a second transceiver placed from the first transceiver. The system determines the position of the second transceiver. The second transceiver has a second clock that provides a second reference signal. A first sequence of pulses are transmitted from the first transceiver. The first sequence of pulses are then received at the second transceiver and the second transceiver is then synchronized with the first sequence of pulses. A second sequence of pulses are transmitted from the second transceiver. The first transceiver receives the second sequence of pulses and the first transceiver is synchronized with the second sequence of pulses. A delayed first reference signal is generated in response to the synchronization with the second sequence of pulses. A time difference between the delayed first reference signal and the first reference signal is then measured. The time difference indicates a total time of flight of the first and second sequence of pulses. The distance between the first and the second transceiver is determined from the time difference. The direction of the second transceiver from the first transceiver is determined using a directional antenna. Finally, the position of the second transceiver is determined using the distance and the direction.

    摘要： A positioning device according to one embodiment of the present invention comprises: a communication unit for receiving, from an external device, a position information message including position information about the external device; a first positioning unit for generating first positioning information including global navigation satellite system (GNSS) coordinate information and/or information about distance to the external device; and a second positioning unit for generating second positioning information by using the position information message of the external device and the first positioning information, wherein the position information message is a broadcast message, and the position information about the external device is real time kinematics (RTK) positioning information obtained by correcting GNSS coordinates of the external device through an RTK correction signal.

    摘要： In accordance with a first aspect of the present disclosure, a localization system is provided, comprising: a plurality of ultra-wideband (UWB) communication nodes; a plurality of antennas, each one of said antennas being included in one of said UWB communication nodes; an antenna selection unit configured to select a subset of said antennas for use in ranging operations that output a position estimate of an external device; wherein the antenna selection unit is configured to select said subset in dependence on at least one previous ranging operation. In accordance with a second aspect of the present disclosure, a corresponding method of operating a localization system is conceived. In accordance with a third aspect of the present disclosure, a computer program is provided, comprising computer-executable instructions that, when executed by a localization system, cause said localization system to carry out a method of the kind set forth.
