Required by IMO Resolution A.817 (19), IEC 61174, and related IHO (International Hydrographic Office) standards. ECDIS is a real-time geographic information system and accepted as equivalent to paper chart for continuous monitoring of the ship’s position using several positioning systems. It should be type-tested and approved by an official authority and should be used only together with official data and regular updates. Useable charts are derived from an official ENCs (Electronic Navigational Charts) database. This displays electronic charts, navigation lines, ARPA data, user-defined information and offers vessel route planning and continuous monitoring. Accurate position, depth, alarm data and other warning facilities assure the vessel of reliable route monitoring and contributes greatly safer to vessel navigation and efficiency as well as reduced operator workload when compared to using traditional paper charts. The system is composed of monitor and processor unit. Please contact your local supplier for further information.
