From Voyager 1 and 2 near- and far-encounter data, a very precise localization of the sources of Saturn radio emission is found with no a priori hypothesis on the emission directivity, by assuming only that there are two sources of emission, each emitting in one circular polarization, and that the global variation of the polariztion are due to occulations of the sources by the planet. This and the previous localization results do not allow one to decide between various models of the emissions source.
