abstract = {The research on space ad hoc network technology is of great significance in improving the space topology adaptability of spacecraft formation, reliability of inter-satellite links and fault tolerance of satellite networks. As space missions are placing increasingly higher requirements for the scale of constellations and multi-star coordination capabilities, scientific researchers have conducted in-depth research on the spacecraft ad hoc network technology and achieved remarkable results. This paper mainly sorts out the topological configuration, link characteristics and orbital configuration of spacecraft networking missions, and analyzes the characteristics and development trends of spacecraft networking. At the same time, the technologies that are applied to the field of spacecraft ad hoc network are introduced, including the time-frequency synchronous measurement technology based on node topology planning, the networking routing technology for active cognition of multi-domain information in the network, and the ad hoc network communication technology based on phased array agile beam pointing. Finally, some open issues and their development trends are also discussed, which can provide reference for subsequent researchers in this field.}
