AbstractThe GNOS (GNSS Occultation Sounder) instrument on FY3 (Feng-Yun-3) meteorology satellite is a GNSS (Global Navigation Satellite System) radio occultation payload for remote sensing of Earth's neutral atmosphere and the ionosphere. GNOS's first flight mission is on-board the Chinese FY3C meteorological satellite, which was launched at 03: 07 UTC 23 September 2013. GNOS was switched on 5 days later. From then, GNOS could receive more than 700 (500 GPS + 200 BDS) radio occultation events per day on a global basis. GNOS provides vertical profiles of atmospheric temperature, pressure, and humidity, as well as ionospheric electron density of the earth. These data are being used for NWP (numerical weather prediction), space weather, climate and ionospheric research. GNOS will also be on-board the follow-on FY3 satellites in the future. Some improvements will be implemented, including extended occultation channel number, open loop tracking for L2C and B1I, optimized antenna pattern and so on. This paper focuses on the GNOS design and characteristics for FY3D satellite, which is planned to be launched in 2016. The instrument performance derived from analysis of measurement data in laboratory and mountain-based occultation experiments at Mt. Wuling in Hebei Province is presented. The improvements of GNOS on-board FY3D were validated.
