dc.description.abstractOne of the most challenging tasks at the early stage of satellite programs is fitting various stowed satellite configurations within different launcher envelopes to dissipate heat from the satellite. To overcome this thermal challenge, this paper proposes a practical launcher thermal analysis tool (PLTAT). The aim of this tool is to predict satellite dimension and the launcher type based on the heat dissipation requirement. The study focused on three-axis stabilized geostationary communications satellites, and north and south panels were used for heat dissipation by radiation. The remaining panels of the satellite were covered by a multilayer insulation. In the calculations, the solar arrays were placed at the north and south panels while antennas were placed at the east and west panels. The values obtained by the Excel-based VBA were compared with flying GEO satellites. Heat dissipation values calculated using PLTAT were compared with existing radiative area results. The minimum difference between the existing values and the PLTAT calculated values was 0.63%, whereas the maximum difference was 12.04%. The results from calculated PLTAT radiative areas were in agreement with existing radiative areas. Thus, PLTAT can be an alternative and useful approach when designing three-axis stabilized geostationary communications satellites.en_US
