Problems solved by technology

However, the traditional Simulink simulations are all offline simulations, which are only suitable for the preliminary verification of complex spacecraft control algorithms. The real-time performance of the algorithm cannot be guaranteed, and it cannot truly and reliably reflect the situation of the control algorithm in the actual operation of the spacecraft.
