The Xi'an Satellite Control Center will exercise an east-west orbital control to FY-4B from 08:16 to 08:44 August 2nd, 2022 (UTC). During the period, ground receiving stations shall cease to receive the cloud imageries sent by FY-4B from 08:16 to 08:44 (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.
