Phase-B thermal control subsystem design for the ESEO satellite

The objective of this thesis work is the Phase-B design of the thermal control subsytem on the ESEO satellite. The ESEO project is a mission created by the Education Satellite programe of the European Space Agency (ESA). The ESEO project is an opportunity created by ESA to allow students from varous European universities to collaborate and get a hands on experience on developing and doing actual feasibilities studies on a satellite. The initial part of this work is relevant to the nature of the ESEO project and gives a bried description of its requirements, mission phases and payloads. Afterwards the mathematical model used for the thermal model are studied because these are the foundations of the thermal softwares used to model ESEO. The two main tools used for the creation of the thermal model are MiniTAN and ESATAN with its important radiative module ESARAD. The second phase consists of the hypothesis taken and the materials and data used in order to create a proper model. The design steps are described and the satellite is then inserted into its orbit so as to create a simulation of the actual thermal heat uxes it is exposed to. Once properly designed the results were analyzed and the model was adjusted in matter to satisfy all thermal requirements. The model was then margined and the results listed.
