Detailed Thermal Design and Control of an Observation Satellite in Low Earth Orbit
Öz: The thermal environment in space presents challenging conditions, including vacuum, low pressure, atomicoxygen, and extremes of hot and cold. Satellites consist of electronic equipment which needs to be maintainedwithin a certain temperature range during the operation period. The thermal design and control of observationsatellites in low Earth orbit (LEO) are therefore very important. In our study, we present the thermal design andanalysis of LEO observation satellites. A satellite was designed and modelled using Systema Thermica v.4.8.P1software with the Monte-Carlo ray tracing method. Analyses were performed for two extreme scenarios with (i)extreme hot and (ii) extreme cold temperatures. The areas, temperatures, and locations of the radiators on thesatellite panels were analysed under the hot scenario, while the power and operating conditions of the heaterswere evaluated based on the cold scenario. As a result, in the hot condition, a total radiator area of 0.6972 m2was used. The cold condition required a heating power of 25.06 W for the most critical battery in the satellite.It was observed that the temperatures of the electronic equipment on the satellite must be within the desiredtemperature range throughout the observation process. This temperature range is different for each type ofequipment; for instance, batteries need to be between 0°C and +30°C, while electronic equipment must bebetween −20°C and +50°C.
