Pegasus delivered the GALEX, NuSTAR, IRIS, CYGNSS, ICON, and IXPE missions.
The potential of GNSS reflectometry for land sensing was demonstrated by the TechDemoSAT-1 and CYGNSS missions.
CYGNSS was developed with support from NASA’s ESTO and has provided critical hurricane-forecasting data since 2016.
NASA’s Cyclone Global Navigation Satellite System (CYGNSS) is a set of eight smallsats launched in 2016 that demonstrated the use of reflected GNSS signals for studying tropical weather systems.
CYGNSS was recently approved for an additional three years of operation.
CYGNSS provides daily soil moisture data products used for hydrological studies and disaster monitoring.
CYGNSS measures the strength of GPS signals reflected by the Earth's surface and has been operational since December 2016.
NASA launched eight 30-kilogram Cyclone Global Navigation Satellite System (CYGNSS) satellites in 2016 that were built by the Southwest Research Institute and the University of Michigan.
SMAP’s radiometer provides 30-kilometer resolution and SMAP’s radar provides three-kilometer resolution, compared with roughly 500-meter resolution for CYGNSS.
