Thermal Control Design for the Combination of Star Sensor Using C-C Graphite Material

To solve the problem that thermal control design of the combination of star sensor is high requirement and difficult to implement, the thermal control design of the combination of star sensor using C-C graphite material was proposed in this paper. By taking some combination of star sensor requiring difference in temperature on bracket of star sensor less than 4.5 degrees C and temperature of flange of star sensor in 8.5 +/- 2 degrees C as an example. Thermal analysis was achieved to validate the thermal control design scheme proposed in the paper. Analysis results show that the thermal control design scheme can make difference in temperature of bracket of star sensor in orbit less than 2.73 degrees C, and flange of star sensor in orbit between 7.47 degrees C and 8.93 degrees C, which meet the temperature requirement very well. The design scheme is reasonable.
