Abstract The use of satellites for navigation, geodesy and altimetry requires a precise knowledge of their orbits. Satellite orbits are commonly derived from Doppler counts of radio signals propagating to/from the satellites. However, corrections must be applied to these measurements to account for the presence of the ionosphere. The first order ionospheric perturbation term is usually eliminated by the use of dual frequency systems. However, the higher order terms have to be taken into account. In this paper, a correction model is described for the second and third order perturbation terms. The entries of the model are the estimates of the first order terms given by dual frequency systems. On the basis of computer simulations, it is shown that a significant reduction of the total ionospheric error can be achieved with this technique.
