Abstract
A location system includes transmission reception devices. A first transmission reception device is configured to operate as a stationary unit of the location system for localizing tag devices by exchanging ultra-wideband signals. The tag devices is localizable within a localizing space that extends along a high-resolution line associated with the first transmission reception device. The system also includes a movable unit and first and second tag devices that are positioned at the movable unit and are separated from each other by a tag separation distance. A control system is configured to perform an ultra-wideband signal analysis to determine the distance from a selected tag device to the first transmission reception device and to derive an orientation of the movable unit with respect to the high-resolution line from distances determined for the first tag device and the second tag device.
