AIS Secure Class A System The AIS Secure Class A System can operate in three different modes: - Standard Mode Silent Mode Secure Mode The VDL 6000 AIS Secure Class A system provides SOLAS com- pliance and BSH-certification at very attractive prices. The data link communication covering identity, position, desti- nation and other required static, voyage-related and dynamic data which gives all vessels in an area increased situational awareness and improves safety at sea for the individual ship. The AIS Class A System for naval operation can be configured in "receive only" mode or both "receive and transmit" mode for positive identification and positioning of all ships in the vicinity. The secure system builds on existing AIS technology and sup- ports a user to receive, schedule and transmit encrypted mes- sages to other users. This can include transmission of secure text messaging and to receive encrypted range and bearing. The secure AIS can also support simulated targets for naval The SOTDMA technology is used in the AIS transponder which transmits and receives information on all vessels within VHF co- verage. This information includes position, identity, course over ground, heading, and rate of turn as well as navigational status and destination of the ship. The information received from, and provided to, the ships is easily plotted on any ARPA radar or electronic chart system. The screen presentation of the cal signs of other ships enables a ship to make direct contact with conflicting vessels by text messaging or voice communication. Maximum awareness is accomplished. Easy to install in any ship, the AIS Class A system is connected to a GPS antenna, a VHF antenna and power supply, and is complete after connecting it to the onboard sensors. To maximize the benefit of the investment, the AIS Class A system is delivered with an interface to the chart system and/or ARPA radar. Moreover, the system is designed to support long-range The shipborne AIS Secure Class A system consists of a Trans- ponder and Minimum Keyboard and Display (MKD) unit.
