文章依据“资源三号”卫星三线阵相机在轨工作环境特点,简要分析了三线阵相机热控设计的难点,给出了相应的解决措施,分析并总结了相机的在轨温度场,以相机在轨温度数据验证相机热控设计的正确性。结果表明,相机在轨温度稳定,所有温度均能满足指标要求,证明相机热控设计合理正确。
The article briefly analyzes the difficulty of the thermal control design of the three line array camera and gives the corresponding solutions based on the characteristics of the working environment of the “satellite No.3” satellite triple-line camera in orbit, analyzes and summarizes the in-orbit temperature field, Correct camera thermal control design with camera on-track temperature data. The results show that the temperature of the camera on the rail is stable, and all the temperatures can meet the requirements of the index, proving that the camera thermal control design is reasonable and correct.
