Previous observations have shown the importance of measurements of waves in plasmas around
Jovian moons, especially in the light of recent advances in analysis of whistler-mode waves in the
Earth magnetosphere and their importance for acceleration of radiation belt electrons to relativistic
energies. We analyze whistler-mode chorus and hiss using a database of measurements of the Waves
instruments of the Electric and Magnetic Field Instrument Suite and Integrated Science (EMFISIS)
onboard the Van Allen Probes in the Earth's radiation belts. We estimate the time-frequency
structure, polarization and propagation parameters of these waves. We show that high resolution
multicomponent measurements of the fluctuating magnetic and electric fields are necessary for
proper characterization of hiss and chorus. Proposed measurement modes for the low frequency
receiver subsystem of the Radio & Plasma Waves Investigation (RPWI) experiment, which will be
implemented on the JUICE (JUpiter ICy moon Explorer) spacecraft, include onboard processing
designed to be suitable for a similar analysis of whistler-mode waves in the magnetospheres of
Jupiter and Ganymede.
