TI  - THERMAL DESIGN, ANALYSIS AND TEST VALIDATION OF TURKSAT-3USAT SATELLITE
AB  - When CubeSat projects are a useful means by which universities can engage their students in space-relatedactivities. TURKSAT-3USAT is a three-unit amateur radio CubeSat jointly developed by the Space Systems Designand Test Laboratory and the Radio Frequency Electronics Laboratory of Istanbul Technical University (ITU), incollaboration with TURKSAT, A.S. company as well as the Turkish Amateur Technology Organization. It waslaunched on April 26, 2013 as a secondary payload on a CZ-2D rocket from China’s Jiuquan Space Center to an altitudeof approximately 680 km. The mission of the satellite has two primary goals: (1) to voice communication at Low EarthOrbit (LEO) and (2) to educate students by providing hands-on experience. TURKSAT-3USAT was designed to sustaina circular, near sun-synchronous LEO, and has dimensions of 10 x 10 x 34 cm3. Within the course of this paper,TURKSAT-3USAT’s thermal control will be addressed. TURKSAT-3USAT’s thermal control model was developedusing ThermXL and ESATAN-TMS software. Using this model, temperature distributions of the CubeSat whensubjected to various experimental conditions of interest were computed. Using a thermal vacuum chamber (TVAC),thermal cycling and bake-out testing were carried out on the flight model to verify the thermal design performance andcheck the mathematical model. Based on thermal analysis results, the temperature of equipment was within theallowable temperature range except for the batteries that were between 42.56 oC and -20.31 oC. Heaters were used forthe batteries in order to maintain the batteries’ temperature within the allowable temperature range.
