radiative areas of geostationary satellite are one of the challenging tasks for
satellite thermal engineers at the early stage of the project. Radiative areas
of geostationary communication satellite for the payload and platform panels
are determined based on worst hot case (end-of-life). After calculation of radiative
areas, it needs to be optimized according to worst hot and cold scenario at sun
acquisition mode, orbit raising mode and geostationary orbit. In this study,
geostationary satellite platform panel was considered. The radiator’s dimensions
were calculated and then optimized based on </span> <span lang="en-us" xml:lang="en-us"> </span> <span lang="en-us" xml:lang="en-us">sun acquisition mode, orbit raising
mode and geostationary orbit. Calculated radiative areas both the north panel
and the south panel was 1 m <sup>2 </sup>. Radiative areas were studied at +/-10%
m <sup>2 </sup>. It was seen from the analytical results that the surface
temperature of the platform panel areas were between -48.5 <sup>o </sup>C at 1.1
m <sup>2 </sup> of radiative area and 37.7 <sup>o </sup>C at 0.9 m <sup>2 </sup> of
radiative area. </span> </p>}, number={5}, publisher={Sakarya University}
