Abstract

The verification system for fast autonomous deep-space optical navigation control prototype belongs to the field of semi-physical simulation system based on virtual reality. It includes the autonomous optical navigation control and dynamic simulation system to be verified with the selected landed planet and area to generate the navigation information and control command of deep-space detector to complete the dynamic simulation of the deep-space detector; a target simulating system to generate the 3D virtual environment the deep-space detector faces and to be shown in the display based on the detector information produced through dynamic simulation; and an optical navigation camera system to take the image on the display and to drive the generation of next step of deep-space detector navigating information and control command and complete the dynamic simulation of the deep-space detector.

Description

technical field [0001] The invention relates to a simulation system for autonomous optical navigation control of a deep space probe, which belongs to a semi-physical simulation system based on virtual reality technology. Background technique [0002] With the increasing number of interplanetary exploration missions, autonomous positioning of deep space probes and safe soft landing on the surface of planets have become important tasks and topics for future deep space scientific exploration. Soft landing autonomous navigation control technology refers to the fact that the detector uses the information provided by its own sensors to independently determine the position, attitude and other pose information without the direct participation of people, and at the same time perform safety evaluation on the alternative landing area. During the landing process, the final landing point is selected, and at the same time, the control law is autonomously generated to reach the landing poi...
