The Message Exchange Network System using by Radio Communication
The message exchange network system using radio communication is a message exchange network that can use both satellite and radio communication in order to ensure the continuity of operations. In the event of a fault or failure (individual ship or communication center, etc.) in the real-time satellite-based message exchange network in operation as the main communication network of naval vessels during operations, the system automatically switches to the radio communication network (HF/UHG) by using the communicators in possession.
