面向感传一体天基网络的数字孪生技术OA

To address the requirements of digital twin modeling for space-based networks driven by real traffic and collaborative tasks,a digital twin technology for integrated sensing and transmission space-based networks is proposed.A container-based cyber-physical co-simulation and verification framework is built,which realizes key functions such as virtual-physical interfacing of space-based networks,sensing task simulation driven by real traffic,and protocol verification for inter-satellite cooperative sensing tasks.This approach effectively supports network modeling and task-driven simulation for integrated sensing and transmission constellations.The system supports parallel operation of hundreds of nodes,dynamic configuration of link parameters,and emulation of complex protocol interactions.Moreover,through an external interface,it enables image data exchange and algorithm module invocation between satellite containers and independent servers.Experimental results demonstrate that the proposed framework can carry real service traffic within the simulation network,and accurately reproduce inter-satellite signaling and data transmission processes in cooperative scenarios,providing a feasible technical method for constructing and validating digital twins of integrated sensing and transmission space-based networks.
