Abstract: At present, the research and design of temperature control for star sensor in domestic institutions are less, and they focus on the image processing and image algorithm optimization of star map. The thermal effect of temperature on the star sensor is analyzed in this manuscript by taking the target energy change, signal-to-noise ratio and centroid positioning error as indexes, so as to realize the reliable application of high-precision star sensor in complex space thermal environment. Furthermore, based on the structure and thermal distribution of star sensor, the thermal design and heat dissipation path optimization of star sensor are carried out, and the thermal control measures of TEC are proposed. The temperature distribution of star sensor is discussed in typical high temperature and low temperature conditions. The validity and rationality of the thermal design are simulated and analyzed by finite element simulation software. On the basis of the above analysis and design, a set of temperature control system is completed. By simulating the environmental conditions of the star sensor under high temperature conditions, the thermoelectric refrigeration method is used to cool the star sensor, so that the temperature of the star sensor detector maintains at 20℃±3℃. The relationship between thermal environment factors and image quality is clarified, and the correlation analysis between temperature and star recognition accuracy is completed, which provides a direction for future improvement of star sensor attitude determination accuracy.
