A ULD tracking system monitors the location and serviceability of individual Unit Load Devices throughout their full transport cycle – from loading at the origin airport to unloading and return. Airlines, ground handlers, and freight forwarders rely on it to prevent misrouting, reduce search time at outstations, and accelerate container turnaround. Technology varies by implementation: barcode scanners cover the basics, while RFID tags and GPS transmitters feed real-time data into central asset-management platforms. One important distinction: ULD tracking follows the load carrier itself, not the cargo inside – shipment visibility is handled by separate tracking systems.
