The analysis employs partial derivatives with respect to the dynamical parameters obtained from the ORBGEN module of the Bernese GNSS Software. The SRP-induced accelerations are decomposed into three orthogonal directions: (a) along the satellite to the Sun direction, (b) along the satellite’s solar panel axis, and (c) along the direction completing the right-handed coordinate system. Accordingly, the accelerations are parameterized by three components in each direction, resulting in a total of nine SRP parameters.</p> |
