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.
The Professional Plan besides the numerous features included will allow you to track 1 Vessel of your choice via satellite
The Enterprise Plan will allow you to track unlimited vessels via satellite, and more features
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.
