Abstract: The recent progress of thermal network model correction methods for satellites is summarized and reviewed in this paper. In order to overcome the difficulties such as the insufficient testing data, many constraints and engineering applications, some improvements of the thermal network correction methods based on least square approximation are presented, including parameter correction, graded correction and transient correction methods, and providing some technical references for further research.
