The Message Exchange Network System Using Radio Communication

The Message Exchange Network System using by Radio Communication

Overview of the Message Exchange Network System Using 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.

  • Real-time message exchange network operation in the satellite and WAN/LAN communication sections
  • Switch to radio communication (message exchange system using radio communication) in case of satellite communication failure to ensure continuity of operations
  • Ensuring security by applying compression algorithm and government-class crypto equipment to satellite and radio communication sections
