China launched the first of a new generation geosynchronous meteorological satellites on Saturday. The launch of Fengyun-4A satellite took place at 16:11 UTC using the Long March-3B/G2 (Y42) – or Chang Zheng-3B/G2 per its Chinese name – from the LC3 Launch Complex at the Xichang Satellite Launch Center.
Fengyun-4 (Wind and Cloud) series is China’s second-generation geostationary meteorological satellites after Fengyun-2 satellite series. The performance of Feng Yun-4 has been improved in relation to FY-2 in terms of data amount, network transmission bandwidth, product type and quantity and archiving data and applications.
The satellite attitude is three-axis stabilized to improve the time resolution of observations and regional mobility.

The new generation satellites are designed with an enhanced imagery scanning capability, desirable for monitoring small and medium scale weather systems. It is equipped with vertical atmospheric sounding and microwave detection capabilities to address 3D remote sensing at high altitudes.
The satellite also carries instrumentation for solar observations for extreme ultraviolet and X-rays, in a bid to enhance China’s space weather watch and warning capability.
