Design and Implementation of Spacecraft Digital Twin System

To address the challenges of personnel training, mission scenario validation, and operational status monitoring arising from the rapid escalation of aerospace flight control complexity, this paper designs a spacecraft digital twin system for aerospace personnel training. A four-dimensional logical relationship model for spacecraft digital twins is proposed, alongside a system architecture that integrates real-time data synchronization and high-fidelity simulation. For scenarios including operators training, pre-deployment verification of flight control plans, and real-time operational monitoring, an integrated teaching-rehearsal environment architecture is introduced, which resolves the authenticity limitations of traditional training setups. This framework enables high-fidelity simulation for flight control protocols, facilitates real-time state contrastive monitoring with physical spacecraft, and enhances aerospace control safety.
