Detail:Starting 31/01/2023 09:39:49 S3B will start performing SRAL external calibrations over a transponder site in Leonessa. To conduct this transponder pass, the on-board Digital Elevation Model (DEM) altitude value must be temporarily updated in RAM, and is reverted immediately after the pass. A short outage immediately before and after the pass will be introduced, and data should be considered degraded as per non-nominal acquisition mode, for a total duration of approx.27 seconds over the transponder location (42.61607° N, 13.03780° E) for all relative orbits number (RON) 306 - from cycle 75 (inclusive) onwards.

Revision History:[Original] Small signal level variations with the EUMETCast Europe service have been noticed, which could have differing data reception impacts depending upon the location and antenna size of the user reception station. To mitigate any potential issues, maintenance on the satellite and the uplink service with the contractors is planned on 20 September 2023, with the aim of improving signal levels on the EUMETCast Europe service, provided via EUTELSAT 10B. During the maintenance window, some disruption and short outages to EUMETCast services (BAS, HVS-1 and HVS-2), can be expected. [Rev.1]
