**3. Menu system composition**

Based on the menu design idea, the avionics system can realize the sharing of hardware modules and resources, task migration, and system reconstruction, enhance the tolerance and processing ability of the avionics system for faults, significantly improve the development efficiency and productization degree of the integrated electronic system, and make the integrated electronic system highly reliable. The intelligent spacecraft provides the necessary technical support, mainly including the contents that will be presented in the subsequent sections [12].
