How frequently are voyage-related messages updated in an AIS?

• A. Every 1 hour
• B. Every 30 seconds
• C. Every 5 minutes
• D. Every 15 seconds

Answer: (D)

Voyage-related messages in an AIS (Automatic Identification System) are transmitted every 15 seconds. This frequent updating is essential for maintaining real-time situational awareness and safety in the maritime environment. The 15-second interval allows vessels to communicate critical information such as position, course, speed, and other navigational data, ensuring that nearby vessels and traffic monitoring stations have the most currently available data. This capability helps in collision avoidance and improving overall maritime safety. The other time intervals mentioned, such as 1 hour, 30 seconds, and 5 minutes, are either too long to maintain effective situational awareness or not standard for voyage-related message updates in AIS configurations.
