Abstract: This paper evaluates the potential use of reflected signals from Global Navigation Satellite Systems as a source of opportunity for sea ice permittivity and concentration research, analyses the sea ice data collected in the Greenland disco bay by the European space agency, processes the amplitudes between both polarizations of reflected signals, tracks several different satellites at the same time, and ensures the processing time and the effectiveness of the data. From the polarimetric ratio of Dual polarization of the reflected signals and the simulated complex dielectric constant, it concludes that the parametric ratio has an apparent evolution with the complex dielectric constant.

Key words: GNSS-R, sea ice, polarimetric ratio, permittivity
