Cyclone Global Navigation Satellite System (CYGNSS)

CYGNSS (Cyclone Global Navigation Satellite System) is a space-based system that uses GPS signals from 8 microsatellites to measure ocean surface winds, especially in tropical cyclone regions. By analyzing how these signals are disturbed by ocean waves, CYGNSS provides accurate, real-time data on wind speeds within storms. This information helps meteorologists better understand, track, and forecast hurricanes, ultimately improving safety and preparedness for affected communities. CYGNSS's innovative approach allows for continuous monitoring of storm intensities, even through heavy rain and cloud cover, making it a valuable tool for weather prediction and climate research.
