The Xi'an Satellite Control Center will exercise an east-west orbital control to FY-4A from 1:16 to 1:44 August 25, 2022(UTC). During the period, ground receiving stations shall cease to receive the cloud imageries sent by FY-4A from 1:16 to 1:44(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.
