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 she may appear to be "Out of Range". Satellite-AIS comes as an ideal supplement in such cases.

In order to enable Satellite-AIS tracking, you have two available options:

  • upgrade to a SAT or to a SAT PRO subscription plan

    Depending on your choice of subscription plan you get:

    SAT plan: global coverage for all vessels, 12-hour delay - 15 vessels undelayed

    SAT PRO plan: global coverage for all vessels, 6-hour delay - 50 vessels undelayed

  • purchase SAT Add-ons regardless of your subscription plan and get undelayed global coverage for the number of vessels you choose (max. 15 vessels)
 
What's more, if you are a vessel owner or operator, you can get Enhanced Satellite Tracking using the Inmarsat-C terminal of the subject vessel. Upon activation, you can rest assured that there will be at least one position report during the predefined interval that you have set.
 
 
 

Tip: If you are interested in certain vessels, you can always check whether newer positions of them are available via Satellite-AIS. Simply, go to the respective vessel's Details page. From there, you can see whether newer positions via Satellite AIS are available.

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