The topography element of this mission will serve primarily the marine operational users but will also allow the monitoring of sea ice and land ice, as well as inland water surfaces, using novel observation techniques.The Sentinel-3 mission is designed as a constellation of two identical polar orbiting satellites, separated by 180º, for the provision of long-term operational marine and land monitoring services. The operational character of this mission implies a high level of availability of the data products and fast delivery time, which have been important design drivers for the mission. https://directory.eoportal.org/web/eoportal/satellite-missions/c-missions/copernicus-sentinel-3 language code: en Date=2019-03-26 User Id=sritz Entity=WeightedRelation Operation=INSERT System Note=insert WeightedRelation New Value=id: null related concept uuid: 7204c4d5-b7d0-41af-ba90-61d47c6dc610 relationship type: null relationship value: null generated by: null Date=2019-03-26 User Id=sritz Entity=WeightedRelation Operation=INSERT System Note=insert WeightedRelation New Value=id: null related concept uuid: 4b941002-170e-413b-aee4-860155b891e3 relationship type: null relationship value: null generated by: null Date=2021-01-13 User Id=sritz Entity=PrefLabel Operation=UPDATE Field=text System Note=update PrefLabel Old Value=SENTINEL-3B New Value=Sentinel-3B Date=2019-03-26 User Id=sritz Entity=Definition Operation=UPDATE Field=reference System Note=update Definition Old Value=https://directory.eoportal.org/web/eoportal/satellite-missions/c-missions/copernicus-sentinel-3 New Value=https://directory.eoportal.org/web/eoportal/satellite-missions/c-missions/copernicus-sentinel-3 https://www.wmo-sat.info/oscar/satellites/view/401 Date=2019-03-26 User Id=sritz Entity=WeightedRelation Operation=INSERT System Note=insert WeightedRelation New Value=id: null related concept uuid: 029feed6-79dc-4316-b8ac-be8f1e557f89 relationship type: null relationship value: null generated by: null Date=2019-03-26 User Id=sritz Entity=WeightedRelation Operation=INSERT System Note=insert WeightedRelation New Value=id: null related concept uuid: 9bfd9ff7-b838-4834-bd47-0127384c79f7 relationship type: null relationship value: null generated by: null Date=2019-03-26 User Id=sritz Entity=WeightedRelation Operation=INSERT System Note=insert WeightedRelation New Value=id: null related concept uuid: d81fc4e3-c0b4-4205-82b2-ef2161c169a3 relationship type: null relationship value: null generated by: null Date=2019-03-26 User Id=sritz Entity=Definition Operation=UPDATE Field=text System Note=update Definition Old Value=The Sentinel-3 (S3) mission of ESA and the EC is one of the elements of the GMES (Global Monitoring for Environment and Security) program, which responds to the requirements for operational and near-real-time monitoring of ocean, land and ice surfaces over a period of 20 years.
