In-Orbit Management System for Satellites Based on Digital Twin

Digital twin satellite can receive data from in-orbit satellites for real-time evolution, and provide data feedback to in-orbit satellites. In response to the problems of long project cycles, hard quality control, and high implementation costs exposed by the traditional in-orbit management mode based on physical devices, this paper establishes a highly reliable digital twin satellite, which includes some typical models of subsystems. The digital twin satellite can receive telemetry data from in-orbit satellite and complete the evolution of its own parameters and structure during simulation, ensuring the consistency between the model and the satellite. On this basis, a digital twin of satellite is used as an information carrier to build an in-orbit management system. The in-orbit management system provides a digital solution for information services, data analysis, and decision support. This system is suitable for in-orbit management of single satellite or multiple satellites, and can greatly improve the efficiency and economy of satellite asset management.
