| Zusammenfassung |
| The FORMOSAT-3/COSMIC (Constellation Observing System for Meteorology,
Ionosphere, and Climate) Mission consisting of six Low-Earth-Orbit (LEO)
satellites is the world's first demonstration constellation using radio
occultation signals from Global Positioning System (GPS) satellites. The
atmospheric profiles derived by processing radio occultation signals are
retrieved in near real-time for global weather/climate monitoring, numerical
weather prediction, and space weather research. The mission has processed,
on average, 1400 to 1800 high-quality atmospheric sounding profiles per
day. The atmospheric radio occultation data are assimilated into operational
numerical weather prediction models for global weather prediction, including
typhoon/hurricane/cyclone forecasts. The radio occultation data has shown a
positive impact on weather predictions at many national weather forecast
centers. A follow-on mission was proposed that transitions the current
experimental research mission into a significantly improved real-time
operational mission, which will reliably provide 8000 radio occultation
soundings per day. The follow-on mission, as planned, will consist of 12 LEO
satellites (compared to 6 satellites for the current mission) with data
latency requirement of 45 min (compared to 3 h for the current
mission), which will provide greatly enhanced opportunities for operational
forecasts and scientific research. This paper will address the
FORMOSAT-3/COSMIC system and mission overview, the spacecraft and ground
system performance after four years in orbit, the lessons learned from the
encountered technical challenges and observations, and the expected design
improvements for the spacecraft and ground system for FORMOSAT-7/COSMIC-2. |
