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:
- Purchase The Sat Global Service, to access the most recent satellite positions (depending on the version) for the global fleet.
- or purchase the Sat Flexible Service, to get undelayed global coverage for the number of vessels you choose.
Upon purchasing a SAT product, make sure to activate undelayed satellite tracking for the vessels of interest. Click here to learn how.
Note: 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 detail page. From there, you can see whether newer positions via Satellite AIS are available.
