Evaluation of cygnss gnss-r signal sensitivity to ocean parameters and wind retrieval assesment

The cyclone global navigation satellite system (CYGNSS), launched on December 15, 2016, represents the first dedicated GNSS-R satellite mission specifically designed to retrieve ocean surface wind speeds in the Tropical Cyclone (TC) environment [3], [4]. CYGNSS will use a constellation of eight microsatellite observatories that can receive both the direct and reflected signals from GNSS. These observatories are capable of collecting four simultaneous reflections each, thus providing high temporal-resolution wind speed retrievals within TCs.
