Thermal (THM)

Subsystem Top Level Requirements
-- Maintain the temperature of all satellite components within their normal operating ranges

Because the CubeSat is very small, and therefore does not have excess weight or power available for an active thermal control system, an accurate thermal model was designed. The model separates the 1000 cm^3 cube into 83 different components, providing fine details in the temperature gradients throughout the structure. The model also takes into account solar heat flux, Earth Infrared Radiation, albedo, and the heat generation of high power components such as the PCOMM transceiver. Based on this model, the internal and external components may need to be painted or moved, to maintain allowable temperatures throughout.
