Vessel Tracking with AIS
How ships are tracked worldwide: AIS signals picked up by coastal stations and satellites, cleaned, matched to voyages and used for arrival predictions.

What this diagram shows
- AIS positions come from shore stations and satellites
- Positions are matched to voyages and ports
- Arrival times are predicted from speed and route
Prompt used
Vessel tracking data flow: ships broadcast AIS messages (position, speed, heading). Coastal AIS receivers and satellite AIS providers send them to an ingestion service, which removes duplicates and bad positions and stores them in a time-series database. A voyage service matches positions to vessels, voyages and port calls using a vessel registry. An ETA model predicts arrival times, shown to customers on a map and sent to ports.
