However, in this method, the control of the assembly process is not strict, and the process parameters are not quantitatively controlled, resulting in poor consistency of product assembly accuracy, uncontrollable assembly and adjustment cycle, etc., and poor assembly process, which is not conducive to the improvement of product quality and production efficiency.
[0004] In addition, since the three-axis pointing accuracy requirements of the measurement coordinate system on the detector and the installed reference coordinate system on the prism are transmitted through the base, if the assembly accuracy of the detector is low, the installation offset error of the star sensor will be uncontrollable

Description
technical field [0001] The invention relates to the field of mechanical assembly, and particularly proposes an auxiliary device for realizing six-degree-of-freedom precision glued assembly of star sensor detectors, which is also suitable for mechanical assembly of parts that adopt glued assembly and have three-axis pointing accuracy requirements. Background technique [0002] The star sensor takes the star in the celestial inertial coordinate system as the reference. The star is imaged on the detector through the optical lens to obtain the coordinates of the image point. According to the coordinates of the image point, the star sensor in the celestial inertial coordinate system is calculated. The opto-mechanical component is the executive component of the star sensor imaging, mainly composed of detectors and optical lenses. In addition to the aberration of the optical lens, the factors that cause the coordinate measurement error of the image point of the star sensor are main...
