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 subscription plan and above or one of the selected bundles.
- purchase SAT Add-ons regardless of your subscription plan or bundle and get undelayed global coverage for the number of vessels you choose (max. 15 vessels)
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 Details page. From there, you can see whether newer positions via Satellite AIS are available.
