Real-time navigational information systems for port and harbor operations

Based on present day technology in the measurement of tides, currents, and weather and the new techniques for electronic charting and navigational display systems, the integration of tidal and current sensors into a real-time navigational information system is suggested as a logical step toward a complete shipboard display of all pertinent information needed for ship operations. A general concept for the configuration of a multi sensor real-time navigational information system for ports and harbors is described, as well as the details of the first of such systems now in operation or being planned. Information from such systems has proven to be of real value to piloting and dredging operations, and can be installed using "on-the-shelf" technology.
