Giant planets and their radio phenomena — •Helmut O. Rucker — Space Research Institute, Austrian Academy of Sciences, 8042 Graz, Austria

Novel findings of the Cassini Radio and Plasma Wave Science experiment on the Saturn Kilometric Radiation (SKR), in particular the enigma of the variability of Southern and Northern Saturn hemispheric SKR periodicities, will be addressed. Another highlight of recent discoveries is a new type of periodicity found in the Jovian decametric radio emission (DAM), potentially attributed to specific plasma configurations in the Io plasma torus. And the stereoscopic view of both NASA STEREO spacecraft for the first time enables the unambiguous determination of the origin of radio emission and, in the case of Jupiter DAM their conical beam structure.

The general overview of giant planets radio phenomena will be rounded off by a short introduction in spacecraft radio antenna calibration methods in order to minimize any inherent error in radio data analysis.
