Navigation star tracker is an important part of spacecraft to identify its own position and attitude in space. Its mechanical structure must be able to ensure that it will not produce large stress when it is subjected to vibration and impact during the launch process, which will damage the detection accuracy and imaging quality of the navigation star tracker. At the same time, the spacecraft design is very sensitive to the mass requirements, so the navigation star tracker must be designed to minimize the mass while ensuring the structural strength. According to the design and application requirements of a star tracker, the working conditions of the preliminary design scheme are analyzed by using workbench, and the optimization is carried out according to the analysis results. Under the condition of meeting the service conditions, the optimization results can reduce the structure weight and provide reference for the design of subsequent series.
