All MarineTraffic users have free access to vessels' positions 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.
Note: If you are interested in certain vessels, you can always check whether newer positions of them are available via Satellite-AIS. Please open the respective vessel's detail page. From there, you can see whether newer positions via Satellite AIS are available.
In order to enable Satellite-AIS tracking, you may consider one of our Plans or 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 Global Plan besides the numerous features included will allow you to track up to 10 Vessel of your choice via satellite
As soon as you purchase one of our SAT products, please make sure to add the Vessel/s you would like to track via Satellite under your Fleet and activate the SAT Flex button as described below.
Note II: Through SAT Global service as satellite tracking is activated automatically for all the vessels globally.
Please open the “My Fleet” section of your account and select the Fleet where the vessel was added. Now, you may use the slide bar control to activate the SAT Flex option for the vessel of your interest.
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 be rest assured that there will be at least one position report during the predefined interval that you have set.
Note III: 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.
