Thermal Control Design Conception of the Amazonia-1 Satellite
Keywords:Amazonia-1 satellite, Satellite thermal control, Thermal mathematical model
AbstractAmazonia-1 is a Brazilian remote sensing satellite providing mainly images, in order to observe and monitor deforestation, especially in the Amazon region. This paper describes the thermal control design, which uses passive and active concepts. The active thermal control is based on heaters regulated by software via thermistors.
The passive thermal control consists of multi-layer insulation
blankets and radiators, paints, surface finishes to maintain
temperature level of the overall carrier components within an acceptable value. The thermal control design is supported by thermal analysis using thermal mathematical model. The temperatures and heater power are predicted for critical cases.
