Maritime AIS tracking
Track any
vessel.
Real-time AIS positions, MMSI registry, and country-level fleet data — all in one place.
Real-time positions
Live AIS coordinates, speed over ground, course and heading — updated continuously for every tracked vessel.
MMSI registry
Decode any 9-digit MMSI to its country of registry, flag state, and maritime identity class.
Country fleets
Explore full fleets by flag state. Browse every vessel registered under Finland, Portugal, Germany, and more.
How it works
Vessels broadcast
Every vessel with an AIS transponder continuously transmits its identity, position, speed, and heading on VHF radio.
Signals aggregated
A global network of coastal stations and satellites receives these transmissions and consolidates them into a live data feed.
You explore
Search any vessel, decode MMSI numbers, and track ships in real time — no registration required.
What is AIS?
The Automatic Identification System is a mandatory tracking standard for commercial vessels over 300 GT. Ships broadcast their position every few seconds — VesselStats makes that data browsable.
