Marine VHF Radiotelephone is required to install by the Global Maritime Distress and Safety System(GMDSS). This equipment is used for communication with nearby ship station and/or coast station. It is important to safety navigation. However, since the target ship's name is not known, an effective radio call may not be able to be performed. By using AIS information, a ship can call a target ship more simply and certainly. JRC has developed marine VHF radiotelephone with direct call function by AIS.
