Abstract: The optical efficiency of satellite optomechanical loads is closely related to thermal design, and model correction of their thermal control system is an essential part of thermal design. In recent years, many reference based methods for improving the efficiency and accuracy of thermal model correction based on deep learning and optimization algorithms have emerged both domestically and internationally. However, there is currently no systematic induction. This paper summarizes the new correction methods, and focuses on the analysis of several means to improve the correction effi-ciency in the special problem of satellite optical mechanical load thermal control model correction - appropriate optimi-zation algorithm, building Surrogate model and developing automatic correction tools. A specific analysis was con-ducted on the research progress, applicable conditions, and limitations of these three methods, and suggestions were put forward for the development of correction tools. Finally, prospects were made for the field of satellite optical and mechanical load thermal control model correction, providing direction for improving the accuracy and correction effi-ciency of thermal models in the future.
