英文摘要	The GNOS instruments are GNSS radio occultation payloads for atmospheric and ionospheric sounding onboard FY-3 meteorological satellites. The first GNOS instrument has been in orbit since September 23, 2013 when the FY-3C satellite was launched. The next generation GNOS instrument is being developed for the 3rd batch of FY-3 series satellites. This paper presents the new instrument's characteristics in design and main performance in occultation tracking. We show that the phase center variety is low enough for the choke-ring antenna new designed to increase the accuracy of precise orbit determination. A wide coverage atmosphere occultation antenna and a 65nm technology ASIC are used in the new generation GNOS instrument. The new GNOS instrument will acquire higher quality occultation data due to its better performance.
