External Data Access Options
Under the Copernicus open data policy, reference products and any products derived from them may also be accessible through various external web portals that are not operated or controlled by the Copernicus Programme.
European Collaborating Ground Segment Portals
These are typically mirror collections of Sentinel Reference Products built by national entities, covering national areas of interest, and including specific services or themes. These facilities receive reference products from the core ground segments and/or the Copernicus services subject to a formal agreement.
These portals may be of interest for a user interested in accessing data in their native language, using the services available, or potentially better access speeds depending on the users location. While these portals operate outside the Copernicus Programme, it should be noted that the development of some of these systems were assisted by EU funding.

International Collaborating Ground Segment Portals
These are similar in concept to their European counterparts but are intended to serve their regional users. Like the European collaborating ground segments, these facilities receive reference products from the core ground segments and/or the Copernicus services subject to a formal agreement. These portals were typically created to facilitate access to Copernicus data where good network connections to Europe were challenging.
These portals are operated by national agencies but some received EU funding to assist in their initial development.

Commercial Portals
These typically offer access to reference products along with pay-for-use services that may include cloud computing, access to commercial satellite data, and various tool sets.
Commercial Derived Data Provider Portals
These typically offer pay-for-use services and products that derive from Copernicus reference products and other data sources. These portals typically have a specific theme such as marine applications or asset management.
Governmental Organisation Portals
In addition to the four groups of portals above, there are also a number of governmental organisation portals that offer access to a wide variety of data including Sentinel data.
Provides links to all EUMETSAT's data access mechanisms (including the WEkEO portal). Using these data access mechanisms one can access a large data catalogue including the Sentinel Reference Products.
Offers access to a large catalogue of data, primarily from NASA missions but also including products derived from Sentinel data.
