The European Collaboration for Space standardization

ECSS is an intiative established to develop a single set of consistent space standards for use by the entire European Space Community.

ECSS standards have evolved from the previous 30 years’experience in the management and implementation of European Space Projects.

ECSS has developed through a partership between the European Space Agency. National Space Agencies and European Industry


ECCS Members

Present members of ECSS are ESA (European Space Agency), the National Space Agencies of Canada, France, Germany, Italy, Norway, the Netherlands, the United Kingdom and European space industry represented by Eurospace.

some organization have an Observer role on ECSS e.g. EUMETSAT, CEN


How it works

Is written in consensus by Industry and Agency Experts Define the requirements rather than the means Makes maximum use of existing and commonly used

international standards Illustrates best practice techniques Has flexibility through tailoring

About 150 standards published


ECSS Objectives / FactsECSS Objectives / Facts

Established to:– increase the effectiveness of all space programmes in Europe through

the application of a single set of Standards and Requirements recognised by all potential European Customers and equally accepted by Industry.

– Support the space manufacturing industry in Europe

Primary strength is to facilitate standardization of contract requirements in customer/provider relations throughout all levels of space activities

Recognised and appreciated by all European space entities, non-European space entities and various European and International Organizations for Standards. Several Space Agencies have expressed their interest for using ECSS Documents (Ukraine, Russia, Japan, China, Australia and Brazil).

Catch-up production of standards during past two years (mainly in the engineering branch) has led to an almost coherent and complete set of ECSS standards

Call-up of ECSS as applicable standard in contracts has become a recognised practice in European space business


Users’s Feedback

Users’s feedbacks: Confirmation of approaching the maintenance phase

(less development needed). Identification of points to be improved :

– Standards need to be more focused for direct application to business i.e.

– Avoid mixing requirements, recommendations & informative material

– requirements uniquely identified and verifiable – Resolve incoherencies and inconsistencies in and

across documents.

ECSS to go from development phase to application and maintenance phase


ECSS Steering Board set-up dual task force end 2005 to propose way forward into new phase of ECSS

– Scope TF1: ECSS organizational aspects

– Scope TF2: Contents of ECSS standards

Results and SB deliberations (June 2006): New ECSS Organization:

More user oriented For transitional & maintenance phases With simplified processes and decisional levels With increase ECSS members ownership of product

ECSS Types and Content: 3 Categories of ECSS documens (Standards, Handbook,

Technical Memorandum) Enforcement application of drafting rules Benchmarking phase to complete and review the set of

standards

From development toapplication & maintenance phase

GroupWorking Group

Steering Board (SB):

Delegates from member organisations. Responsible for policy and strategy issues and for overall supervision.

Does not approve individual Standards.

Technical Authority (TA):

Delegates from members organizations.

Set up and implement Work-plan.

Authorize Public Review and approval of documents.

Executive Secretariat (ES):

Performed by ESA/ESTEC.

Provide support to SB & TA. Support WGs in drafting documents in accordance with ECSS rules / procedures.

Custodians of ECSS docs.

Collect and analyze of Change Requests, New Work Items Proposals, feedback …

Overall Monitoring of schedule and budget


ECSS types of documents

ECSS set of documents reorganized according to 3 types of documents Standard

– Normative document written specifically for direct use in invitation to tender and business agreements for implementing space related activities. Its content strictly limited to the statement of verifiable customer requirements, supported by the minimum descriptive text necessary for understanding their context.

Handbook– Non-normative document providing background information, e.g.

orientation, guidelines, technical data, advice or recommendations, which contains information about how to implement space related activities.

– Two types of handbook are considered: 1) Guidelines and good practices 2) Collecion of data

– Note: Handbook contains data recognized as valid for use by the ECSS community.

Technical Memorandum– Non-normative document providing useful information to the space

community on a specific subject, prepared to record and present non-normative data, which are not relevant for a Standard or for a handbook, or not yet mature to be published as handbook or standard.
