What does the integrity status in AIS indicate about the vessel's position?

• A. The accuracy of the ship's speed
• B. The reliability of the ship’s position data
• C. The history of the ship's previous positions
• D. The rank of the ship in traffic

Answer: (B)

The integrity status in the Automatic Identification System (AIS) primarily indicates the reliability of the ship’s position data. This status helps users understand how trustworthy the position information is based on various factors, such as the accuracy of the navigation equipment and the conditions affecting data transmission. The integrity status can alert users to any potential issues with the data, allowing for safer navigation and decision-making. In contrast, the other options do not pertain directly to the integrity status. The accuracy of the ship's speed involves different parameters and does not relate specifically to position reliability. The history of the ship's previous positions is more about tracking past movements rather than assessing current positional integrity. The rank of the ship in traffic pertains to its priority in navigational situations and does not connect to the integrity of positional data. Therefore, the correct answer focuses on the accurate assessment of position reliability, which is crucial for safe maritime operations.
