On January 11, approved by China Meteorological Administration (CMA), FY-2E meteorological satellite (located over 86.5°E) was officially out of operation. During 9-year operation, FY-2E has realized two space shifts, formed network observation with FY-2D and FY-2G successively, and completed 104 thousand times of observations, which has made crucial contribution to meteorological observation in China and Asia as well.

FY-2E is the third operational geostationary meteorological satellite in China. As the follow-up satellite of FY-2C and FY-2D satellites, FY-2E, on the basis of maintaining and succeeding the technical state of FY-2C and FY-2D, has made improvements in 32 necessary technologies like upgrading stray radiation of cloud images.

FY-2E was lifted off in Xichang Satellite Launch Center on December 23, 2008 and was positioned over the equator at 123.5°E. From December, 2009 to the early June in 2015, FY-2E initiated operation at 105°E. From July 2015 to January 11, 2019, FY-2E began operation at 86.5°E.

FY-2E realized space drift on November 28, 2009 and successfully replaced FY-2C which had extended service time, and conducted dual-satellite network observation with FY-2D. FY-2E has realized the dual-satellite positional shift and operational takeover for the first time in the geostationary meteorological satellite history of China.

FY-2E boasts stable technical operation; with visible light image quality somewhat higher than that of FY-2C and FY-2D; stray radiation of infrared imagery down by 30% to 40% compared with FY-2D; with noticeable improvements in calibration accuracy; and has the longest running operation record among geostationary meteorological satellites in China.

After decommissioning, FY-2E will find its application in scientific research experiments and development, and provide remote sensing data service for pre-flood season in South China. (Jan. 17)
