CEOS MISSIONS, INSTRUMENTS, MEASUREMENTS and DATASETS

The CEOS Database is updated annually based on a survey of CEOS member space agencies and has a number of applications.

Information sharing in support of the coordination of future Earth observation mission, instrument and measurements plans.
Earth observation measurement gap analysis - including that performed by the CEOS Systems Engineering Office (SEO).
A connection between the Earth observation user community and satellite-operating agencies of CEOS.
Generation of content for the print edition of The Earth Observation Handbook.

The CEOS Database is updated annualy (usually October/November). It is the only official consolidated statement of the programmes and plans of CEOS agencies. Contents are provided by CEOS agencies, and while best efforts are made to keep the database up to date, information from individual agencies supersedes information presented here.

The database currently features details of 513 Earth observing satellite missions and 941 instruments ((482 distinct instruments, some being repeats), which are currently operating or planned for launch in the next 15 years - funded and operated by around 30 CEOS space agencies worldwide.

	Missions		Instruments (Distinct)
	Operating: Approved: Planned: Considered:	349 70 86 8	Operating: Being developed: Approved: Proposed:	694 (328) 138 (92) 42 (28) 67 (34)

The last CEOS Agency survey was completed in October 2022.
