Between January and April 2018 several changes in the constellation of Meteosat satellites will be made. Meteosat-11 will be taken into operations, moved to 0-deg longitude and take over the main full Earth imagery service over Europe and Africa from Meteosat-10. Following this Meteosat-10 will be moved to 9.5-deg E longitude and take over the operational European 5-minute 'rapid scan' mode service from Meteosat-9. Finally Meteosat-9 will be moved to 3.5-deg E longitude and be available as a 'rapid scan' mode service backup to Meteosat-10.
