Thermal Control of CM and SM Panels for Turkish Satellite

The aim of the thermal design of a satellite is to keep all its components within their specified temperature range. The common design approach is to use a combination of MLI blankets, OSR, CCHPs, heaters, surfaces finishes, paints, and thermistors. Turkish satellite thermal control uses the North and South panels to reject the internal heat dissipation and to limit the diurnal variation because of the minimal solar illumination on these faces. The radiative areas are covered with optical solar reflector (OSR). Sizing of the radiative areas is performed taking account the worst conditions that are maximum heat dissipation, maximum solar illumination (solstices), end-of-life thermo-optical properties.
