“…This torque depends on the principal moments of inertia of the satellite and is inversely proportional to the cube of the satellite geocentric distance. The adopted mathematical model in terms of the quaternion attitude is given in (Zanardi et al 2012) and for the analytical approach is given in (Motta and Zanardi 2014;Zanardi et al 2014).…”

“…To estimate the influence of the aerodynamic torque in the rotational motion, in this paper it is assumed that the velocity is equal to the orbit velocity, the aerodynamic coefficient is fixed, and the thermosphere model TD-88 is used for the atmospheric density (Pisacane and Moore 1994). The adopted mathematical model for the analytical approach is given in (Motta and Zanardi 2014;Zanardi et al 2014) and for the numerical approach in terms of the quaternion is given in (Zanardi et al 2012).…”

“…O TGG ocorre devido ao gradiente de força gravitacional existente entre diferentes pontos do satélite, dependendo da distribuição de massa e da forma do satélite (Pisacane & Moore, 1994), através dos momentos principais de inércia do satélite. Os três componentes médios deste torque no sistema fixo no satélite são discutidas detalhadamente em Chiaradia (2007), Pereira (2011) e Zanardi & Pereira (2012).…”

“…Para o cálculo do ângulo de aspecto solar , utiliza-se o produto escalar entre direção de incidência da luz solar e a direção do eixo de rotação O vetor unitário é determinada pelos ângulos e , sendo que a direção pode ser determinada através da ascensão reta e declinação do Sol.Deste modo o ângulo é dado como demonstrado pelo trabalho [2]:…”
