Optical Navigation Sensor Calibration System Structure Design And Analysis

Along with the our country deep space optical navigation technology development, space flight has become increasingly tend to use optical attitude sensor for aircraft attitude acquisition and measurement. Optical navigation sensor adopts the starlight navigation instead of inertial navigation map, with real-time correction, stable aircraft to replace the single axis or the three axis gyro stabilized platform, currently has been widely applied.Optical navigation sensor calibration system for high precision optical navigation sensor ground calibration system, in order to adapt to the detection accuracy continues to improve, with make a spurt of progress of development. The optical system is used as an optical navigation sensor calibration system is the core part of the barrel, the rationality of the structure design, material selection is correct or not, directly affect the calibration accuracy of high-precision star simulator.By learning the high-precision star simulator working principle, this paper discusses in detail the optical navigation sensor calibration system machine the overall layout of the system. According to the optical navigation sensor calibration system optical system given optical size and alignment requirements, completed the optical navigation sensor calibration system design of the overall structure, focus on the establishment of the high-precision star simulator barrel and its supporting structure of3D simulation model, and the application of finite element software ANSYS environment temperature thermodynamics, self-weight stress, modal analysis, ultimate the results verify the rationality of structure design, to meet the optical navigation sensor calibration system design requirements.
