63 Agencies operating 201 satellites!
In a best-effort organization like CEOS, people, energy, and ideas matter. CEOS depends on its active Members and Associates (collectively known as “CEOS Agencies”) to ensure that key activities have sufficient human resources and seamless leadership at all levels. CEOS Agencies:
- Provide leadership for the Plenary, SIT, Working Groups, and Virtual Constellations
- Power and sustain CEOS activities
- Generate new and innovative ideas and initiatives
Agencies also benefit from CEOS participation as they take part in collaborative missions/data systems and global initiatives to benefit society. CEOS Agencies work together to accomplish specific goals relevant to their own agency and mission priorities.
CEOS Members and Associates are listed below.
