... A parameterized model of perturbing action of solar radiation pressure on the spacecraft motion is described (this model takes into account the shape, reflecting properties of surfaces, and spacecraft attitude). ... The Spektr R spacecraft is a key element of the mission. ... The solar radiation pressure depending on the atti tude of the spacecraft and optical properties of its sur face, is one of the main sources of errors originating when one determines and predicts the spacecraft motion...
