Litton Marine Systems has launched a new IMO-compliant vessel traffic system (VTS) for locks, bridges, ports and coastal waters. The company's new VTS-Master-W is a new system utilizing commercial off-the-shelf (COTS) hardware and proprietary software running under Windows-98/NT. It is based on Litton's unique VTS-Master technology, which permits real-time remote display of raw video data from shore-based surveillance radars superimposed on geographical maps of the area. The modular VTS-Master-W system is of a flexible design and can be expanded from a basic low-cost radar-based traffic observation system into a comprehensive vessel traffic management information system (VTMIS) with multiple radar transceivers and monitoring stations networked via fiber optic cables, telephone lines or VHF/UHF channels. Litton provides a total turnkey package that includes system design, supply and installation of remote radar stations, monitoring stations and networking, as well as training and maintenance.
