The Meteosat Rapid Scanning Service (RSS) is periodically interrupted for short periods of time.
These temporary outages in the service are used to exercise the Meteosat SEVIRI instrument mechanics in Full Earth Scan (FES) mode*, which is required to keep the mechanism in good repair.
The baseline operational period for the RSS is 26 days of continuous rapid scanning, followed by two days of full earth disc scanning, over 11 months per year.
On 27 March 2018 Meteosat-9 stopped RSS, after Meteosat-10 became prime RSS spacecraft. Meteosat-9 now provides gap filling for Meteosat-10.
|Start date||End date||Duration|
|27 May 2019||29 May 2019||48 hrs (Met-9 will provide gap filling)|
|25 June 2019||27 June 2019||48 hrs (Met-9 will provide gap filling)|
|23 July 2019||25 July 2019||48 hrs (Met-9 will provide gap filling)|
|20 Aug 2019||22 Aug 2019||48 hrs (Met-9 will provide gap filling)|
*During Met-10 FES mode, Met-10 image data and meteorological products are not disseminated. Met-9 RSS image data rectified to 9.5°E is disseminated in lieu (but Met-9 RSS meteorological products are not disseminated). Met-10 FES always starts and ends at 9:00 UTC.
**These dates are tentative. Exact dates will be confirmed in the UNS.
Unscheduled outages can occur at any time. Notifications of these are provided via the User Notification Service (UNS)
