AIS relies on which geodetic datum for accurate positional data?

• A. WGS 84 datum
• B. NAD 83 datum
• C. ED 50 datum
• D. UTM datum

Answer: (A)

AIS, or Automatic Identification System, utilizes the WGS 84 datum for accurate positional data. This geodetic datum is a global standard used widely in GPS technology and various applications involving positioning and navigation. WGS 84 provides a consistent frame of reference for geospatial data across the globe, ensuring that positions conveyed by AIS are accurate and standardized regardless of the location. The use of WGS 84 as a geodetic reference is critical for maritime navigation because it enables interoperability among different vessels and shore stations, which is essential for efficient communication and safety at sea. This universal coordinate system enhances the reliability of the positional data used for collision avoidance and situational awareness in marine environments. While other datums like NAD 83, ED 50, and UTM are used in specific regions or contexts, they do not offer the global coverage and compatibility that WGS 84 provides, making WGS 84 the preferred choice for systems like AIS that operate on an international scale.
