Course 908: The Consultative Committee for Space Data Systems (CCSDS) Training Fundamentals

The Consultative Committee for Space Data Systems (CCSDS) was formed in 1982 by the major space agencies of the world to provide a forum for discussion of common problems in the development and operation of space data systems. It is currently composed of ten member agencies, twenty-three observer agencies, and over 100 industrial associates.

Since its establishment, it has been actively developing Recommendations for data- and information-systems standards to a) reduce the cost to the various agencies of performing common data functions by eliminating unjustified project-unique design and development, and b)promote interoperability and cross support among cooperating space agencies to reduce operations costs by sharing facilities.

This course covers CCSDS's goals and benefits, end-to-end data syetms, space data system physical interfaces, space data system functional model and recommendations.
