The Xi'an Satellite Control Center will exercise an east-west orbital control to FY- 4B from 8:16 to 8:44 March 28, 2024(UTC). During the period, ground receiving stations shall cease to receive the cloud imageries sent by FY- 4B from 8:16 to 8:44(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.
