Análise do Torque de Pressão de Radiação Solar e do Torque Aerodinâmico com Dados Simulados do Satélite CBERS

ABSTRACT

The growth in the number of launches of artificial satellites for the most different functions has motivated studies related to control, propagation, and orbit and attitude determination activities. In this paper a study of the Solar Radiation Pressure Torque (SRPT) and Aerodynamic Torque (AT) of the CBERS (China-Brazil Earth Resources Satellite) satellite is done when the models used in the satellite mission are considered. The results showed that for satellites in Low Earth Orbit (LEO), as in the case of CBERS, the AT has more relevant effects on the satellite’s superfıcie than the SRPT. These results could be useful for satellite supervision and control in post-launch, and are vital for attitude and orbit control of the CBERS satellite.
