Inland AIS System

IDC-AIS Inland System is based on our well proven AIS Class A system and developed in accordance with the latest inland AIS standard requirements. The Inland system is type approved by Fachstelle der WSV für Verkehrstechniken FVT.

The data link communication covers standard AIS messages such as identity, position, destination and other required static, voyage-related and dynamic data as well as blue sign messages for inland navigation for increased situational awareness and improved safety for the individual ship.


The SOTDMA technology used in the AIS transponder transmits and receives information on all vessels within VHF coverage. This information includes position, identity, course over ground, heading, and rate of turn as well as navigational status and the destination of the ship.

IDC-AIS transponder broadcasts Inland blue sign status messages for upstream or downstream navigation; ships passing on starboard side, hazardous cargo carriage (Blue Cones); and estimated time of arrival at locks, bridges and terminals.

Lock management, information on draught, type of cargo and destination is vital for decision making and safe manoevering along the inland waterways. The information received from, and provided to, the ships is easily plotted on any ARPA radar or electronic chart system. This gives the Officer of the Watch a situational awareness and an constant information update that could never be achieved prior to AIS.

Configuration and interfaces
IDC-AIS Inland system is easy to install onboard any ship by connecting it to a GPS and VHF antenna. The installation is complete after connecting it to the onboard sensors.

To maximise the benefit of the investment, IDC-AIS Inland system is delivered with an interface to the Inland ECDIS and/or ARPA radar.

The Inland AIS System consists of Transponder, Minimum Keyboard & Display (MKD), and Connection Unit.
