Europe's Galileo signals used for ocean remote sensing in space

Surrey Satellite Technology Ltd and the University of Surrey have succeeded in detecting a weakly reflected Galileo signal off the ocean surface using the GPS Reflectometry Experiment on one of SSTL’s small satellites, UK-DMC. The reflection was received off the North coast of Australia on 4th November 2007, and the shape of the reflection gives an indication of the ocean roughness, and hence the weather at that place and time (where the wind speed was around 22 km/h, or 14 mph).
