TI  - Optimized Analytical Solution of Platform Panel Radiative Area Dimensioning of Geostationary Communications Satellites: A Practical Approach
AB  - Determining radiative areas of geostationary satellite are one of the challenging tasks forsatellite thermal engineers at the early stage of the project. Radiative areas of geostationarycommunication satellite for the payload and platform panels are determined based on worst hotcase (end-of-life). After calculation of radiative areas, it needs to be optimized according toworst hot and cold scenario at sun acquisition mode, orbit raising mode and geostationary orbit.Authors, in this study, optimized geostationary satellite platform panel. The radiator’sdimensions were calculated and then optimized based on sun acquisition mode, orbit raisingmode and geostationary orbit. Determining radiative areas of GEO satellite is important task.Radiative areas always are determined based on hot case condition at EOL. On the other hand,these radiative areas needs to be optimized according SAM, ORM, and GEO scenario.Calculated radiative areas both the north panel and the south panel was 1 m2. Radiative areaswere studied at +/-10% m2. It was seen from the analytical results that the surface temperatureof the platform panel areas were between -48.5 oC at 1.1 m2 of radiative area and 37.7 oC at 0.9m2 of radiative area.
