Abstract: This paper introduces the development of command and control in unmanned ground system formation operations at home and abroad, summarizes and analyzes the top-level design, product and technology development rules and trends of command and control intelligence of unmanned ground system formation operations. The focus is on the continuous improvement of single platform intelligence level and the development of cluster intelligence. Furthermore, eight key technologies are analyzed, including architecture and interoperability, intelligent perception and decision-making, collaborative task processing, parallel command and control. It is pointed out that the development of intelligent command and control systems in formation operation is an important task for the development of unmanned ground systems.
