COSMIC-2B (Polar)
COSMIC-2B (Polar)
| NOAA / UCAR | Considered | | | This is a radio occultation mission supporting meteorology and ionosphere & climate measurements. The 12-satellite COSMIC-2A/2B constellation (6 equatorial and 6 polar) will produce over 4 times the daily total of occultation events as COSMIC-1 (3000 versus 12,000). This provides the capability to reconstruct the 3D ionospheric electron density structures for ionospheric space weather monitoring within a dramatically short data accumulation period. TGRS will receive signals from GPS, Galileo, and Glonass. COSMIC-2B will be a ride-share mission; the listed orbital parameters are desired and TBC. At present, the U.S. portion of the COSMIC-2B program is unfunded.
