In the complex environment of modern warfare, the increasing volume and diversity of data, the expansion of operational domains, and the need for rapid and accurate decision-making have created significant challenges for traditional command and control systems. Integrated multi-domain command and control has emerged as a modern approach aimed at achieving convergence among land, maritime, air, space, and cyber domains while optimizing information collection, processing, and utilization within an integrated network-centric structure. In this context, space technologies provide capabilities such as wide-area coverage, reliable communications, rapid data transmission, and enhanced situational awareness, which contribute to improving the effectiveness of command and control systems significantly and effectively. This study proposes a conceptual model for integrated multi-domain command and control by leveraging space technologies. The proposed framework explains the relationships among information flow, communication infrastructure, situational awareness, and decision-support processes and can serve as a foundation for future research and advanced defense systems.
