VDL 6000 AIS Class A System The VDL 6000 Class A system provides SOLAS compliance and BSH-certication at very attractive prices. The data link communication covering identity, position, destination and other required static, voyage-related and dynamic data gives all vessels in an area increased situational awareness and improves safety at sea for the individual ship. Positive identication and positioning of all ships in the vicinity reduce the unnecessary “ship on my port bow” calls. Less information overload greatly enhances safety at sea. Features The SOTDMA technology used in the AIS transponder transmits and receives information on all vessels within VHF coverage. This information includes position, identity, course over ground, heading, and rate of turn as well as navigational status and the destination of the ship. The information received from, and provided to, the ships is easily plotted on any ARPA radar or electronic chart system. This gives the Ocer of the Watch a situational awareness that could never be achieved prior to AIS. Information on draught, type of cargo and destination could also be used to make decisions related to manoeuvring. The screen presentation of the call signs of other ships enables a ship to make direct contact with conicting vessels by text messaging or voice communication. Maximum awareness is always accomplished. Conguration and interfaces Easy to install in any ship, the VDL6000 Class A system is connected to a GPS antenna, a VHF antenna and power supply. The mandatory installation is complete after connecting it to the navigation GPS, gyro and installing the Pilot Plug interface. To maximise the benet of the investment, the VDL6000 Class A is delivered with an interface to the chart system and/or ARPA radar. Moreover, the system is designed to support long-range reporting via satellite. The shipborne Class A system consists of Transponder, Minimum Keyboard & Display (MKD), and Connection Unit.
