COSMIC-2: The future of global navigation satellite system - remote observation (GNSS-RO) sensing

摘要

COSMIC is a joint U.S.-Taiwan 6-microsatellite demonstration mission that was launched in April 2006. It is the world's first operational GPS radio occultation (RO) mission for global Earth weather forecast; climate monitoring; atmospheric, ionospheric, and geodetic research. The GPS-RO data has been demonstrated to be valuable to the climate, meteorology, and space weather communities. COSMIC has proven to increase the accuracy of the predictions of hurricane/typhoon behavior, significantly improve long-range weather forecasts, and monitor climate change with unprecedented accuracy. COSMIC will reach the end of its design life in 2011, and the critical capability it provides will begin to degrade as satellites become no longer operational. As a result, NOAA and NSPO intend to jointly develop and launch COSMIC-2, a high-reliability next generation follow-on system. COSMIC-2 is will provide the next generation of global navigation satellite system (GNSS)-RO data to users who critically rely on it.
