Committee on Earth Observation Satellites

The Committee on Earth Observation Satellites (CEOS) is an international coordination body established in 1984 to facilitate cooperation among space agencies operating Earth observation satellite systems.

CEOS consists of 35 organisations as Members (operating or planning Earth observation satellites) alongside 32 organisations as Associates. Membership across both categories spans over 35 countries, as well as numerous intergovernmental organisations.

While membership is restricted to national or international organisations, non-members may participate in thematic and technical activities. Commercial, academic and non-governmental organisations participate in Working Groups and Virtual Constellations.
