A system combining very high frequency radio communication with automatic identification system capabilities offers enhanced situational awareness for maritime operations. This technology allows vessels to transmit and receive data such as identity, position, course, and speed, while simultaneously providing a channel for voice communication. As an example, a commercial ship can use it to broadcast its location to nearby vessels and port authorities, while also communicating verbally with a harbor pilot.
The integration of these two technologies is significant for improving safety and efficiency at sea. It allows for proactive collision avoidance, facilitates search and rescue operations, and enhances vessel traffic management. Historically, VHF radio was the primary means of short-range maritime communication, but the addition of AIS provides a digital data layer that greatly expands its functionality. This evolution has resulted in a more comprehensive and reliable system for maritime communication and navigation.
