Objectives and Applications 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. The actual launch date in dependent upon the scheduling and success of the new Falcon Heavy launch vehicle. The April 2018 launch date is a "no earlier than" date.
