Autonomous navigation flight control system for deep space impact

Abstract

The invention belongs to the technical field of deep space exploration, aims at solving problems of poor autonomy, a low integration degree and overlarge size and weight of a current space detector, and relates to an autonomous navigation flight control system for deep space impact. The system comprises a first bearing device and a second bearing device which are separately arranged, and the firstbearing device is internally provided with a flight control and information processing module, a space navigation camera module, an inertia measurement module, an energy module, an attitude and orbitcontrol execution module and a wireless communication module which are in communication connection with one another; and the flight control and information processing module can make the attitude andorbit control execution module complete a preset flight task based on image information collected by the space navigation camera module and inertia sensitive information detected by the inertia measurement module. The second bearing device is driven by the power device to rotate along an axis of the second bearing device, and the first bearing device can rotate and separate relative to the axis of the second bearing device. In the invention, lightweight, miniaturized and integrated autonomous flight control of a space exploration aircraft can be realized.

Description

technical field [0001] The invention belongs to the technical field of deep space exploration, and in particular relates to an autonomous navigation flight control system for deep space impact. Background technique [0002] Deep space impact detection technology has strong scientific exploration and technological innovation, and has important strategic significance for the development of the country in the field of deep space. The impact detection of deep-space targets can obtain information such as the internal components, geological structure, and radiation characteristics of the target celestial body, provide rich data for the study of the origin of life and the evolution of the universe, and provide a priori guarantee and support for the safe landing of landing probes. [0003] At present, there is no mature flight control system for deep-space impact detection in China. The traditional deep-space exploration space vehicle control system has a single function and perform...
