MSC Cruises has worked with independent software design company Quality Positioning Services (QPS) on a high performance, real-time vessel track, trace and emergency monitoring system. This voyage planning and monitoring system (VP & MS) allows MSC Cruises to implement route analysis and track each of its ships with an update rate of one second and an accuracy of less than five metres. The system means that each ship is constantly sending information, including its own position, speed, heading and course together with all other ship targets within a 40 mile radius, to the shore based QPS Connect server in Sorrento. In order to provide a reliable traffic image, the QPS Connect server fuses the real-time vessel information with real-time information from terrestrial based AIS networks.
