Could the acquisition_station of the downlinked satellite data (e.g. eop:acquisitionStation in OGC 10-157r4 and OGC 17-003r2) be added to this extension or it this avaiolable in a different extension (could not find it)? Often encoded in OGC 10-157r4 as eop:EarthObservation/eop:metaDataProperty/eop/:EarthObservationMetaData/eop:downlinkedTo/eop:DownlinkInformation/eop:acquisitionStation.
