| 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. |

| Detail: | Starting 02/02/2023 10:28:30 S3B will start performing SRAL external calibrations over a corner reflector site in Spain. To conduct this 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.26 seconds over the transponder location (42.052°N, 0.7300° E) for all relative orbits number (RON) 335 - from cycle 75 (inclusive) onwards |

| Detail: | Starting 14/02/2023 20:35:57 S3A will start performing SRAL external calibrations over a transponder in Leonessa, Italy. 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.28 seconds over the transponder location (42.61607° N, 13.03780° E) for all relative orbits number (RON) 270 from cycle 95 (inclusive) onwards |
