During this period all instruments will experience a data outage except telemetry data from MAG which will continue to be sent. After the maneuver, all instruments and products will resume nominal production and distribution.
All ABI channels will experience navigation and product quality degradation for a period of time up to 30 minutes due to the Kalman filter reset. There is no back up date for the yawflip. It will be conducted during a critical weather day.
