(02 Jun 2021) Rocket: Chang Zheng-3B; Payload: Fengyun-4B (FY-4B); Date: 2 June 2021, 1617 UTC; Launch site: Xichang Satellite Launch Center, China. The satellite was deployed into a 195 km x 38,507 km x 28.52 km geosynchronous transfer orbit.

FY-4B will be used in the fields of weather analysis and forecasting, and environmental and disaster monitoring, state media said.

The satellite, based on the SAST-5000 platform, and rocket were developed by the Shanghai Academy of Spaceflight Technology (SAST) and the China Academy of Launch Vehicle Technology (CALT), respectively. Both belong to the China Aerospace Science and Technology Corporation (CASC).

Each FY 4 satellite has a mass of approximately 5,300 kg and is designed to operate for at least five to seven years. FY-4B carries the same suite of four meteorological instruments as FY-4A, which was launched in December 2016.

The China Meteorological Administration (CMA) is responsible for the construction and operation of the satellites' ground application system.
