How can I get more updated vessels' positions?

All MarineTraffic users have free access to vessels' positions as recorded by our network of terrestrial AIS-receiving stations. However, the typical range of them is limited to a certain distance. Thus, if a vessel is sailing in a remote area it may appear to be Out of Range.  In such cases Satellite-AIS comes as an ideal supplement as it can help you track a vessel even when it is sailing in the middle of the ocean.

In order to enable Satellite-AIS tracking, you may consider one of our Plans or a single service, depending on your business needs: 

  • the Sat Global Service will allow you to access the most recent satellite positions (depending on the version) for the global fleet

  • the Sat Flexible Service will allow you to get undelayed global coverage for the number of vessels you choose

  • the Professional Plan besides the numerous features included will allow you to track 1 Vessel of your choice via satellite

  • The Professional Plus Plan besides the numerous features included will allow you to track up to 10 Vessel of your choice via satellite

Upon purchasing a SAT product, make sure to activate undelayed satellite tracking for the vessels of interest. Click here to learn how

Note: Satellite-AIS tracking may be less effective if the subject vessel is equipped with a Class B AIS transponder. Such units are smaller, simpler and lower cost compared to Class A transponders but their signal is weaker making it harder for satellites to pick-up AIS messages coming from them.
