An innovative approach for thermal analysis and design of small satellites consisting in the study of its thermal behavior and properties from a global perspective is investigated in this research project. Spacecraft analysis and design is usually carried out in a tailored manner, based on the particular characteristics of each mission. The increasing interest in PocketQubes as space platforms, which share multiple design features, opens the possibility to develop general thermal control procedures applicable to multiple satellites independently of their payloads, configurations and orbits, within certain ranges. An exploration of the design and environmental parameters that influence the thermal behavior of picosatellites is carried out along with a sensitivity analysis in order to better understand their influence on temperatures. The Delfi-PQ satellite has been chosen as a case study for which a finite element model has been developed using ESATAN. As well, a Matlab tool has been developed for processing the data generated. Based on the results produced from these analyses, generalized conclusions on how thermal control could be achieved for satellites such as the Delfi-PQ and similar PocketQubes are derived. This study aims to set the basis for approaching thermal control of highly standardized spacecraft from a global perspective, opening new possibilities of lowering the costs and increase its reliability and performance. The outcomes and lessons learned could be later applied to other categories of similar satellites such as CubeSats.
