Abstract: The attitude and orbit control technologies for constellation systems were reviewed, focusing on aspects such as autonomous orbit determination, constellation configuration maintenance, high precision orbit control, attitude pointing control and angular momentum management. The technical challenges faced by the application of existing attitude and orbit control methods in the Queqiao CNRS were analyzed. The future research trends for attitude and orbit control technology were predicted, and suggestions were made for the development of components in attitude and orbit control systems, based on potential mission implementation requirements of constellation systems.
