The remote sensing SAR satellites have built two rate level distributed information networks for the control, information transmission, and operational management of the entire satellite system. The article introduces the satellite’s requirements for ease of use and ease of use. It adopts layered and distributed autonomous task management architecture, providing users with advanced task interfaces and shielding the internal design status of the satellite, greatly simplifying satellite control. To meet the requirements of stable operation of satellites in orbit, task management measures such as autonomous task conflict and merging have been adopted. Finally, the testing verification and in orbit application of remote sensing SAR satellites in the development process of autonomous mission management system were introduced.
