How often do vessel positions get updated?

Vessel positions get updated as soon as a fresh AIS signal is being received.

Vessels that are within range of our terrestrial AIS stations get frequently updated and are shown in real time. 

Vessels that sail far away from shore, can be covered by using satellite AIS. The position updates may vary from a few minutes up to several hours. This depends on traffic, weather and also other factors.
