             abstract = "The analysis of solar radiation pressure force and its influence 
                         on the motion of artificial satellites has been developed by 
                         researchers. Accurate models to describe the influence of the 
                         Earth's shadow on the torque and force due to solar radiation 
                         pressure have been presented. In this work the solar radiation 
                         torque (SRT) and its influence on the attitude of an artificial 
                         satellite are taken into account by the introduction of the 
                         Earth's shadow function in the equations of motion. This function 
                         assumes a unitary value when the satellite is in the fully 
                         illuminated region of its orbit, and the value zero for the full 
                         shade region. The main objective of this study is to analyze the 
                         magnitude of SRT using the equations described by quaternions 
                         during a 35 day period and to compare the results with the 
                         satellite transition through the shadow region and the time 
                         interval in this region. The duration and transition through the 
                         shadow region were obtained using the software {"}Shadow 
                         Conditions of Earth Satellites{"}. The formulation is applied to 
                         the Brazilian Data Collection Satellites SCD1 and SCD2, and the 
                         torque model is presented in terms of the satellite attitude 
                         quaternion, distance of the satellite to the Sun, orbital 
                         elements, right ascension and declination of the Sun.",
