Optimal Layout Design of a Satellite Considering Thermal Control Subsystem Constraints

In this paper, in order to minimize the required power of satellite thermal control subsystem, considering known geometric model and the orbital parameters and conditions, the optimal layout design of the satellite subsystems will be performed based on thermal and attitude control constraints. Since all of the satellite subsystems can act only in a certain temperature range, here, by considering the thermal dissipations of each subsystem and incoming thermal loads to each satellite faces in different orbital conditions, by optimally layout of components and sub-systems of the satellite, we will arrive to appropriate configuration plan. The constraints of the thermal subsystem should be satisfied by considering the temperature distribution within the satellite as far as possible. Finally, given that the main purpose of this layout is to provide thermal power, in addition to satisfication of the power budget system constraint, the power of the thermal control subsystem has been reduced by 66%. The superiority of this method is that by following the resulting layout, we obtain a model that needs a thermal control subsystem with less complexity and limited power. Consequently, in addition to decreasing the mass of the satellite, reliability will also be increased. Considering the importance of satellite stability, the layout algorithm and optimization are defined in such a way that the attitude control requirements are observed with the thermal requirements in this layout.
