When a space camera works on the track, it presents in vacuum environment, under the condition of low temperatures, the camera can only maintain its temperature level by absorption of radiation. If stayed in this environment for a long time, mechanical structure of the space camera may become brittle, lose strength, and an exfoliation phenomenon may appear, in addition, abnormal operation and malfunction of electronic equipments may also occur, these may affect imaging quality of the camera. In this paper, a heating control method is designed for a space flight off-axis camera. Firstly, heating control working platform of the camera is introduced, a design method of heating control is determined. After that, heating control treatment procedure is introduced. Finally, the ground temperature monitor is used to validate correctness of the method designed. The comparison diagram before and after thermal analysis and temperature data obtained from experiments are presented, results show that, the heating control method is simple and effective, it has wide applicability and strong generalization performance.
