Design of a Digital Twin for Spacecraft Network System

In order to ensure the stable operation of spacecraft in orbit, ground physical twin systems are usually set up, which work synchronously with the spacecraft in orbit. Aiming at the problems of difficult maintenance, long mission preparation time and high operation cost of spacecraft physical twin systems, a digital twin system of the spacecraft network is proposed, which can analyze and evaluate the performance of the network system quickly and efficiently for different tasks. The experimental results show that the digital twin system is consistent with the physical twin system, and can significantly improve the efficiency of ground accompanying flight.
