AIS, which stands for Automatic Identification System, is a real-time tracking system that enables ships of all sizes, including small fishing boats and large container ships, to automatically identify and monitor each other.
How Often Does AIS Transmit?
AIS transmits data every few seconds, depending on the type of vessel and its speed. The frequency of transmission can vary between 30 seconds for slow-moving vessels to as often as every 2 seconds for fast-moving vessels.
Why Does AIS Transmit So Often?
AIS transmits data frequently because it is essential for the safety of navigation. By constantly updating its position, speed, and course, AIS allows other vessels to track each other’s movements and avoid collisions. This is especially important in busy shipping lanes or areas with limited visibility.
What Data Does AIS Transmit?
AIS transmits a variety of data, including the vessel’s name, type, length, width, draft, and destination. It also transmits information about the vessel’s position, speed, course, and heading. This data is used by other vessels to determine the risk of collision and take appropriate action if necessary.
Conclusion
In conclusion, AIS transmits data frequently to ensure the safety of navigation. By constantly updating its position, speed, and course, AIS allows other vessels to track each other’s movements and avoid collisions. This system is essential for all types of vessels, from small fishing boats to large container ships.
