What does this value mean?
The Data received on/last update timestamp shows the exact date and time the vessel's last AIS position signal was received by the MarineTraffic network. It is displayed in your local UTC offset, so the time adjusts based on your device's timezone settings.
This allows you to quickly assess how current the vessel's position is before relying on it for any decision.
Why does update frequency vary?
AIS transmission frequency is not constant — it depends on the vessel's speed and navigation status
Vessels moving at higher speeds transmit more frequently. A vessel that has not updated its position for a long time may have switched off its AIS transponder, be out of coverage range, or be experiencing a technical issue.
