Investigation on the Effects of Various Parameters on the Thermal Control of a Small LEO Satellite

Satellite thermal control ensures safe operating temperature ranges for satellite components, throughout the satellite mission. Effects of satellite altitude, spin rate, and position of satellite radiator on the thermal control of a small Low Earth Orbit (LEO) satellite have been studied. Results show that change in satellite altitude, in the range considered here, does not produce critical thermal conditions. However, satellite spin rate has a marked influence on temperatures. Also, comparison of results for the satellite configurations considered in this study suggests that a radiator at top provides better thermal design conditions. Results also indicate the adequacy of this design methodology for use in satellites with similar missions and orbital parameters.
