What type of data does the Class A AIS Position Report transmit regarding the ship's position?

• A. Static position only
• B. Position with accuracy indication
• C. Position without integrity status
• D. Historical position data

Answer: (B)

The Class A AIS Position Report is designed to transmit the ship's position along with an indication of the accuracy of that position. This means that not only is the geographic location of the vessel shared, but it is accompanied by information that helps to determine how accurate that reported position is. The accuracy indication is crucial for assessing navigation safety, enabling other vessels and shore-based stations to understand the reliability of the position data being received. Understanding this aspect is essential for maritime navigation, as it assists in risk management and decision-making processes. Accurate positioning data helps in collision avoidance and enhances situational awareness for all vessels in the vicinity. The other types of data mentioned, such as static position, position without integrity status, and historical position data, do not provide the same level of real-time navigational safety and situational awareness that is established by including an accuracy indication in the position report. This differentiation is vital in understanding how AIS systems contribute to safer and more efficient maritime operations.
