The satellite was transferred from the State Administration of Science, Technology and Industry for National Defence (SASTIND) to the China Meteorological Administration (CMA).
The new satellite "Fengyun-II G" will improve China's weather monitoring and early warning for natural disasters such as typhoons, rainstorms, sandstorms and forest fires, said a SASTIND statement.
Compared with previous Fengyun-II satellites, the latest has higher accuracy, a shorter observation interval and a longer life, state-run Xinhua news agency reported.
