Abstract :
SuRGE is a low-Earth orbit satellite proposed for an 8-month mission to establish the possibility of spaceborne bistatic GPS remote sensing of ocean surface wind speed/direction, sea surface elevation and soil moisture. Equipped with two GPS reflection instruments and three downward-looking antennas, SuRGE is optimized to validate this measurement technology. Through a nadir facing high-gain (~ 20 db) antenna, a delay and Doppler mapping receiver will continuously record and process GPS reflections. Using this same antenna an analog translator will capture GPS reflections, downconvert the signals and rebroadcast them to properly equipped ground stations where the data can be post-processed to also retrieve the ocean and land surface properties
