A new satellite remote sensing technique has been proven effective in measuring ocean wind speed in order to better track hurricanes and cyclones. This technique uses GPS technology to send signals to Earth’s surface and gather data via Global Navigation Satellite Systems-Reflectometry (GNSS-R) and is expected to lead to better forecasts in the future.
