Goniopolarimetry of the inner heliosphere radio emissions with the STEREO Spacecraft

The S/Waves instrument onboard the 3 axis stabilized STEREO spacecraft is composed of a set of 3 monopole antennas connected to a radio receiver. The receiver measures spectral and cross-spectral power densities on one, two or three antennas in the frequency range between 10 kHZ and 16 MHz. This package therefore have goniopolarimetric (GP), aka direction-finding, capabilities, allowing to determine the direction of arrival of an incoming wave, its flux and polarization properties. We present the first result GP results on solar radio bursts and terrestrial auroral radio emissions.
