During the transition phases parallel dissemination for the 0 degree service and the Rapid Scan Service (RSS) will be provided for specific periods.
Full Earth Scan (FES)
Meteosat-11 will be relocated to 0 degree longitude. In order to support user transition, there will be a four-week parallel dissemination of Meteosat-10/11 SEVIRI Level 1.5 image data and meteorological products:
- Two weeks with Meteosat-10 as prime FES spacecraft
- Two weeks with Meteosat-11 as prime FES spacecraft
See Dissemination Timeline below.
Meteosat-10 and Meteosat-11 orbital positions will be changing during the parallel dissemination phase. The Level-1.5 image data of both spacecraft will be rectified to 0 degree longitude.
Rapid Scan Service (RSS)
For provision of the RSS Meteosat-10 will be relocated to 9.5 deg E longitude.
In order to support user transition, there will be a two-week parallel dissemination of Meteosat-9/10 RSS SEVIRI Level 1.5 image data and meteorological products:
- One week with Meteosat-9 as prime RSS spacecraft
- One week with Meteosat-10 as prime RSS spacecraft
See Dissemination Timeline below.
Meteosat-9 orbital position will be changing during the parallel dissemination phase. The Level-1.5 image data of both spacecraft will be rectified to 9.5 deg E longitude.
