ULTRA-WIDEBAND INDOOR LOCATION SYSTEM AND METHOD

摘要

An ultra-wideband indoor real-time location system (201) is disclosed for determining positions of mobile tag devices within a localizing area. The real-time location system includes a plurality of UWB signal transmitters (MB, BS1,...) located at preset positions and defining the localizing area, wherein the UWB signal transmitters (MB, BS1,...) operate with synchronized clocks and are configured to transmit UWB signals (LFs_MB,...) based on a UWB frame format, wherein the UWB frame format includes unique information content for the UWB signal transmitter locally/respectively emitting the UWB signals (LFs_MB). The real-time location system includes further at least one mobile tag device (T) including a signal reception unit (249) configured to receive UWB signals (LFs_MB,...), a time detection unit (229 A) configured to derive respective arrival time points (ToA1_T,...) for the received UWB signals, an identification unit (229B) configured to derive the unique information content from the received UWB signals (LFs_MB,...), and a control unit (229C) configured to process the unique information content and the arrival time points (ToA1_T) for at least a subset of UWB signal transmitters (MB, BS1,...) in a localizing algorithm to derive the position of the mobile tag device (T) with respect to the subset of the UWB signal transmitters (MB, BS1,...).
