The invention provides an asset-tracking system (100) for tracking a target tag (10) in a space (500), wherein the target tag (10) is configured to emit a target beacon signal, wherein the asset-tracking system (100) comprises a plurality of listener nodes (110) arranged in the space (500) and configured to detect the target beacon signal, wherein the asset-tracking system (100) comprises a control system (300), wherein the control system (300) has access to (i) listener location data and to (ii) map data, wherein in an operational mode: the control system (300) determines the presence of an object (200), wherein an object tag (210) is associated to the object (200), and wherein the object tag (210) is configured to emit an object beacon signal, wherein the plurality of listener nodes (110) are configured to detect the object beacon signal and to provide a related object signal to the control system (300); the control system (300) determines a confidence zone set (230) for each listener node (110) based on the related object signal, the listener location data and the map data; the plurality of listener nodes (110) detect the target beacon signal and provide a related target signal to the control system (300); and the control system (300) determines a target tag location of the target tag (10) based on the related target signal, the listener location data, the map data, and the confidence zone sets (230) of the plurality of listener nodes (110).
