Description

technical field [0001] The invention relates to spacecraft attitude control technology, and is a star sensor image detector assembly. Background technique [0002] The star sensor takes the star as the measurement target, images the star on the image detector through the optical system, and sends the output signal to the data processing unit through A / D conversion, and determines the optical axis vector of the star sensor through star point extraction and star map identification The orientation in the inertial coordinate system is determined by the installation matrix of the star sensor on the spacecraft to determine its three-axis attitude in the inertial coordinate system. The star sensor is generally composed of a hood, an optical system, an image detector component and its circuit, a data processing circuit, a secondary power supply, software (system software, application software, and star catalog), a main structure, and a reference mirror. [0003] The structure of th...
