Abstract: Traditional command and control systems are mostly based on the hierarchical structure of the troops, whose relationship between different subsystems is relatively fixed. These weaknesses make it difficult to adapt to the requirements of the command and control system for joint operations in terms of adaptability and coordination. An overall design method based on the "cloud-network-end" command and control system is proposed. Key technologies involved in the command and control system for all-domain joint operations are analyzed. The deployment and use mode of this system are given. It can provide technical insights for related researchers of command and control system for all-domain joint operations.
