Features of Inland-AIS

Information to be transmitted / received

AIS-equipped vessels transmit each other their own vessel information. The data is also received by the shore stations. They recognize the vessels' identifications and send the vessels the safety-related data including local weather warning and water level information.

EMMA (European Multiservice Meteorological Awareness) provides the ships with the inland AIS devices with the weather warning (e.g. fog, flood, snow and ice), which will be utilized for the safe navigation.
