AB: The High Frequency Receiver (HFR) of the Radio and Plasma Wave Science experiment (RPWS) experiment has direction-finding (DF) capabilities, i.e. it allows us to retrieve quasi-instantaneously the direction of arrival of an incoming wave, its polarization state and its flux. We use these DF capabilities to characterize the source position and polarization state of the main kronian radio emission: the SKR (Saturnian Kilometric Radiation). We expose a full polarimetric study of the southern SKR sources. We also show the localization of the region of emission which confirms that the northern emission is right-handed and the southern one is left-handed, which is compatible with the Cyclotron-Maser Instability emission process. We also observe a possible O-mode radio emission coming form the southern hemisphere of Saturn.
