A Survey of Autonomous Astronomical Navigation Technology for Deep Space Detectors

In deep space exploration, the use of radio measurement and control alone has limitations in accuracy, real-time, and coverage. As an effective complement to radio monitoring and control, autonomous astronomy navigation is one of the key technologies to ensure the success of deep space exploration missions. Facing the urgent needs of deep space exploration for autonomous astronomy navigation, the basic principles of autonomous astronomical navigation for deep spaced spacecraft are outlined, and the research progress of deep space spacecraft self-guided astronomy navigation is briefly introduced, and the key technologies and trends in navigation of the deep space spacecraft autonomous astronomy are analyzed and explored. The analysis results can provide reference for the development of astronomy navigation system for deep space exploration in China, and provide assistance for the overall design of deep space exploration missions.
