Recently, it is informed that all functions, performances, and indicators of FY-3D meteorological satellite have conformed to in-orbit delivery conditions.

FY-3D is the satellite-pm of CMA’s second generation polar orbiting meteorological satellites, with 10 advanced remote sensing devices onboard. Hyperspectral Infrared Atmospheric Sounder (HIRAS), Hyperspectral Near-infrared Greenhouse gases Absorption Spectrometer (GAS), Wide Angle Aurora Imager (WAI), and Ionospheric Photometer (IPM) are newly developed and are for the first time onboard the satellite. Medium Resolution Spectrum Imager (MERSI), as the core instrument, has been markedly upgraded and enjoyed a higher level of performance.

After into operation, it will form network observation with FY-3C satellite, bearing vital significance for the second generation polar orbiting meteorological satellites to making the transition from experimental application to operational service. In the meanwhile, this satellite will effectively underpin global monitoring, forecasting, and services, and push forward Beidou navigation system and meteorological remote sensing satellite technologies to service Arab states development.

On December, 11, 2017, FY-3D has formally kicked off in-orbit testing. The satellite and effective payloads have gone through 3-phase, more than 6-month in-orbit testing. The results have indicated that the satellite system is smoothly functioning with benign performances. All functions, performances and indicators outstrip those of FY-3A, FY-3B, and FY-3C. (Aug. 17)
