Investigating the Factors Affecting the Choice of Thermal Control Coatings in Satellite Radiators

One of the challenges facing satellites is the satellite thermal control process. The mission of the satellite thermal control system is maintaining the temperature of the satellite's components in the permitted temperature range during the satellite mission. Because the radiation is the only way to exchange heat in vacuum, so the surface coating of the radiators plays the most important role in this field. On the other hand, the environmental conditions of the vacuum and the satellite orbit strongly affect the external surfaces, including the radiator surface, such as ultraviolet radiation and charged particles, contamination, micrometeoroids and the erosion of atomic oxygen. This research aims to guide and facilitate the selection of radiator coating for satellites with various missions, such as student satellites, Telecommunication, Weather, radio-television, research, military, etc. To fully examine the role of factors Effect on the radiator coating and the comparison between the current coatings of modern satellites.
