Cyclone Global Navigation Satellite System
CYGNSS is a NASA Earth Venture mission built as a constellation of eight microsatellite observatories. Each uses reflected navigation-satellite signals to measure ocean-surface roughness and wind speed, providing frequent observations through heavy rain in the tropical latitudes where cyclones form and intensify.

- Description
- CYGNSS is a NASA Earth Venture mission built as a constellation of eight microsatellite observatories. Each uses reflected navigation-satellite signals to measure ocean-surface roughness and wind speed, providing frequent observations through heavy rain in the tropical latitudes where cyclones form and intensify.
- Launch Site
- Outcome
- All eight CYGNSS observatories were deployed successfully and contacted after launch. The constellation began frequent measurements of tropical ocean winds, improving coverage of storm inner cores and supporting research on cyclone formation, intensification, air-sea exchange, flooding, soil moisture, and related Earth-system processes beyond its two-year prime mission.
