Summary:The invention relates to a system for tracking the location of a container using a CSS. The system for tracking a location of a container using a CSS comprises: at least four fixed nodes installed at respective predetermined reference coordinate points; at least one mobile node attached to the container to transmit/receive signals to/from the fixed nodes; and a central controller which controls the fixed node to measure the distance between the fixed node and the mobile node through said transmitted/received signals, and to measure the location of the mobile node on the basis of the measured distance. L'invention concerne un système pour effectuer le suivi de la position d'un contenant à l'aide la modulation CSS. Le système de suivi de la position d'un contenant par modulation CSS comprend : au moins quatre noeuds fixes placés à des points de coordonnées de référence prédéterminés respectifs; au moins un noeud mobile relié au contenant pour émettre/recevoir des signaux vers/à partir des noeuds fixes; et un contrôleur central qui commande le noeud fixe pour mesurer la distance entre le noeud fixe et le noeud mobile par l'intermédiaire des signaux transmis/reçus, et pour mesurer la position du noeud mobile sur la base de la distance mesurée.
