Abstract: With the rapid development of society and technology nowadays, the pattern of modern war has turned into the systematic confrontation of the Joint All-Domain, where it includes the domains of land, sea, air, space, cyberspace, electromagnetism, and so on. Joint operation and cross-domain coordination have become the important research topics which help to obtain the victory mechanism of future war. The conceptual connotation, important issues and key technology of planning and control for joint operation action cross-domain coordination are deeply analyzed. The planning and executive control problems for cross-domain action coordination are focused on. From different command and control modes, two types of key technologies, the centralized cross-domain coordination planning and control technology, decentralized cross-domain coordination planning and control technology are proposed. Then, the demand background, running framework and core implementation methods are expounded in detail to provide the important technical support for effective implementation of cross-domain coordination action under joint battlefield environment.
