COSMIC/FORMOSAT-3 (2006)
The Taiwan-US COSMIC mission launched six satellites with GNSS radio occultation receivers, the first operational constellation of its kind. The satellites measured how navigation signals bend through the atmosphere, producing temperature and moisture profiles used in weather models worldwide.
The data improved hurricane track forecasts and global weather prediction within months of launch.
COSMIC proved radio occultation's value and set the standard for the technique commercial providers now use.
COSMIC demonstrated the scientific value of the data PlanetiQ now sells commercially.
