A maritime communication device combines Very High Frequency (VHF) radio functionality with an Automatic Identification System (AIS) transponder. This equipment allows vessels to transmit and receive voice communications on designated maritime channels and simultaneously broadcast and receive identification and navigational data. An example includes a unit installed on a small fishing boat that enables the captain to communicate with nearby vessels and coastal stations while also transmitting the boat’s position, speed, and heading to other AIS-equipped ships and shore-based monitoring stations.
The integration of these two technologies offers significant advantages for maritime safety, situational awareness, and efficient navigation. Its importance stems from its ability to enhance collision avoidance by providing real-time information about surrounding vessel traffic. Historically, VHF radio served as the primary means of short-range maritime communication, while AIS was later introduced to augment safety through electronic identification and tracking. The combination streamlines operations, reducing the need for separate devices and consolidating critical information into a single interface.
