Joint computation of aerodynamic and radiation forces acting on spacecraft

Small satellites are opening radical new possibilities for space utilisation, especially in low-Earth orbit (LEO). Due to their compactness, many small satellites have no active attitude control systems. A method for passive stabilisation would be useful to regulate attitude without requiring the mass and volume of powered sensors and actuators. In this paper, passive aerodynamic stabilisation of a 3U nanosatellite is investigated using an in-house coupled orbit-attitude simulation platform. The objective is to evaluate the robustness of satellite stabilisation in the 200-400 km altitude range, including in the presence of a perturbing magnetic torque, and initial spin motion. The results show that at 400 km altitude, aerodynamic stabilisation is not a realistic method for attitude control, but that its potential increases lower in the atmosphere.

Abstract. In this paper, we discuss the problem of determination of light radiation pressure force upon an anisotropic surface. The optical parameters of such a surface are considered to have major and minor axes, so the model is called an orthotropic model. We derive the equations for force components from emission, absorption, and reflection, utilizing a modified Maxwell's specular-diffuse model. The proposed model can be used to model a flat solar sail with wrinkles. By performing Bayesian analysis for example of a wrinkled surface, we show that there are cases in which an orthotropic model of the optical parameters of a surface may be more accurate than an isotropic model.
