Which data types would you commonly find on an NMEA 2000 network?

• A. Position (latitude/longitude), vessel heading, COG, SOG, depth, water temperature, engine parameters, and autopilot commands.
• B. Weather radar images, email messages, file transfers, and video streams.
• C. Soil moisture, crop yield, rainfall, and pesticide levels.
• D. Keyboard input, screen brightness, CPU temperature, and audio volume.

Answer: (A)

NMEA 2000 networks carry navigation and vessel-systems information that ships’ instruments routinely share. Position data (latitude and longitude) is fundamental for charting and routing, while vessel heading indicates the direction the bow is pointing. COG (course over ground) and SOG (speed over ground) describe how you’re moving over the earth, which is essential for tracking progress and making navigational decisions. Depth data comes from depth sounders, and water temperature provides environmental context for operations and comfort. Engine parameters keep an eye on performance and health, and autopilot commands are messages that control steering automatically. These data types represent the core, day-to-day information marine instruments exchange on an NMEA 2000 network. The other options include items that aren’t part of the typical NMEA 2000 data set. Weather radar images, emails, file transfers, and video streams would require much higher bandwidth and are not how NMEA 2000 is designed to function. Similarly, soil moisture, crop yield, rainfall, and pesticide levels pertain to agriculture, not marine navigation. Keyboard input, screen brightness, CPU temperature, and audio volume relate to general computer or device settings rather than marine sensor data.
