The Xi'an Satellite Control Center will exercise an eccentricity orbital control to FY- 4B from 0:00 to 1:00 and from 11:50 to 12:50  March 26, 2025(UTC). During the period, ground receiving stations shall cease to receive the cloud imageries sent by FY- 4B  from 0:00 to 1:00 and from 11:50 to 12:50(UTC). Under a normal circumstance, the imageries’ positioning accuracy will see some bias within 24 hours after the orbital control. Please forgive the inconvenience caused.
