Abstract
The current study presents the thermal control design of the 3U Cubesat “Pakal” from “Misión Colibrí”. As part of the design requirements, a thermal analysis was carried out to study the effects of the space environment over the spacecraft. This was achieved by making a lumped parameter approach in the critical thermal cases and studying the effects of environmental heat fluxes on each critical component. The model was verified using Thermal Desktop software. Then a Passive Thermal Control (PTC) was proposed to keep critical components at their operating temperature. The proposed PTC consists of two types of passive control: thermal coatings and single-layer insulation.
