Embodiment Construction

[0046] The following is a detailed description of exemplary embodiments of the present disclosure. The exemplary embodiments described therein and illustrated in the accompanying drawings are intended to teach the principles of the disclosure to enable those skilled in the art to make and use the disclosure in many different environments and for many different applications. Therefore, the exemplary embodiments are not intended and should not be considered as a limiting description of the scope of patent protection. Rather, the scope of patent protection shall be defined by the appended claims.

[0047] The present disclosure is based in part on the recognition that in the layout of a hall, such as in a warehouse or storage hall, multiple elongated locating spaces may be affected by locating procedures. Since the extended positioning space may extend over a large distance, reducing precision dilution will require a large number of fixed units placed along the extension of the ...

Abstract

A Location system includes a plurality of transmission reception devices (9, 9A, 9B), wherein a first transmission reception device is configured to operate as a stationary unit of the location system for localizing tag devices (15, 15A, 15B) by exchanging ultra-wideband signals (10), and the tag devices are localizable within a localizing space (5) that extends along a high-resolution line associated with the first transmission reception device. The location system further includes a movable unit (7, 7A, 7B) with the first and second tag devices (15, 15A, 15B), wherein the first tag device and the second tag device are positioned at the movable unit separated from each other by a tag separation distance. The location system includes a distance determination unit (13) configured to determine the distance (D1_A, D1_B; R1, R2) from the selected tag device to the first transmission reception device. The distance determination unit is further configured to derive an orientation of the movable unit.

Description

technical field [0001] The present disclosure generally relates to (indoor) positioning systems. Furthermore, the present disclosure relates generally to positioning systems based on ultra-wideband signal exchange, and in particular to positioning systems that allow identification of the orientation of a mobile unit within the positioning space of such a positioning system. Background technique [0002] Indoor positioning systems are generally based on stationary units (also referred to herein as stationary transmitting and receiving devices) and mobile units (also referred to herein as tags or tag devices). While the position of fixed units is known by the positioning system as a preset fixed (reference) position, mobile units are usually attached to mobile units and are thus movable and can be moved or shifted, changing their position in Locate the position within the space. The positioning system is configured to determine the location of the mobile unit. When a mobile...
