AIS - Automatic Identification System is an aid to navigation to help ships avoid collisions, as well as assisting the rescue services and port authorities to better control sea traffic.
The system is based on AIS (Automatic Identification System). As from December 2004, the International Maritime Organization (IMO) requires all vessels over 299GT to carry an AIS transponder on board, which transmits their position, speed and course, among some other static information, such as vesselís name, dimensions and voyage details. Smaller vessels can also be fitted with AIS to help them see and be seen.
The transponders send data about the vessel in digital format using VHF radio with a GPS (Global Positioning System) receiver, which collects position and movement details.
The map is using AIS data collected by Marine Traffic from "Sharers" who send the AIS data they receive to the Marine Traffic server to give an overall view of shipping around the globe.
Vessel positions may be up to one hour old or incomplete. Data is provided for informational only and is not related by any means to the safety of navigation.

Coverage around Cornwall coast is very limited, do not be alarmed if vessels suddenly vanish or appear, as they are either leaving or entering an area covered by an AIS receiving station.
