3. 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

4. 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

5. 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

6. ECSS 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

7. ECSS to go from development phase to application and maintenance phase
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.

to application and maintenance phase

8. From development to application & 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

10. 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.
