The real-time message exchange network developed based on real-time context data sharing and collaboration is a system that allows up to 500 people to chat with one another simultaneously using the wired, radio and satellite communication systems.
The importance thereof is increasing by the day for the military, where accuracy and promptitude in relation to context awareness of military operations, sharing of context data, decision-making, and command and control are of the utmost importance. The latest systems developed by GDL System enable real-time information exchange and communication using HF/UHF/VHF communication equipment in case of satellite network failure.

• The ROK Navy’s real-time wired/radio communication message exchange network of the
• Joint real-time message exchange network of the ROK Navy and Coast Guard
• Submarine context data sharing system
• Message processing system for commercial satellites

This is the main command and control network of the ROK Navy that provides efficient command and control functions through real-time context data sharing and collaboration among the units engaged in the operations.

In the event of satellite communication failure, the survivability of the command and control network is ensured by switching to a radio-based message exchange network, which is a preliminary communication network for the satellite-based real-time message exchange network.

This is a real-time system for the Navy and Coast Guard to perform the operations and collaborate efficiently based on an interconnection with the real-time message exchange network of the ROK Navy.

The command and communication network (Inmarsat) of submarines is used to share various information and context data (text, voice, video, etc.) for tactical use in operations.

This is a command communication network for naval vessels dispatched overseas to perform operations and training missions in areas outside the range of communication of the military satellite communication system. It ensures communications survivability and improves the capability to perform the assigned missions.

In the case of the naval vessel/aircraft position identification system, MOSCOS, a satellite command network operated by the ROK Navy, was used to to set up a satellite HUB system (geographical redundancy) for YUB support, and new satellite antennas, satellite modems, and terminals were installed on 22 YUBs to establish a nautical chart-based YUB position identification system. The scope of application of the real-time message exchange network in operation was expanded to enable real-time positioning and text-based chatting with YUBs to enable fast and accurate communication and efficient command and control. Also, the individually operated helicopter location tracking system and non-KNTDS naval vessel position information transmission system have been serially interconnected so that the target information from the naval vessel/aircraft position identification system to be linked with the KNTDS and performance-improved KNCCS system through serial communication.
