Structure Design of TUUSAT-1A Microsatellite

TUUSAT-1A stands for Taiwan Universities United Satellite NO.1A. The micro-satellite research team includes scholars from Tamkang University, China Institute of Technology, National Formosa University, National Taiwan Ocean University and National Chia Yi University. The micro-satellite is 28 cm in height and weighs 40 kg and it is powered by solar energy. For image acquisition using GPS and CMOS sensors as payload, the satellite must operate at an altitude of 500 km and at an inclination of 0 21 with the circular orbit for a period of 3-12 months. The structural subsystem is one of the major sub-systems of this satellite. The major functions of the satellite structure include decrease and preserve against compressive strength, support the space, and the requirements for other sub-systems. In this paper, we discuss the structure design of TUUSAT-1A. Key-Words: structure sub-system, TUUSAT-1A, micro-satellite, compressive strength, solar energy.
