During summer 2015, two experimental campaigns in the framework of the Mistrale Project have been carried. In those campaigns a complete GNSS-R sensor was installed on an ultralight aircraft, allowing gathering polarimetric GNSS-R data. The flights were done in France over the Camargue area (flooded areas, marshlands and water salinity changes), and Pech Rouge area (agricultural plots).The estimated reflection coefficients acquired during the flights, have been computed and geo-referenced on ground, showing that the reflection coefficients are sensible to terrain changes. Main results are presented in this work.
