▽ Membership/Participation FAQs

► How do I become a member of CCSDS?
CCSDS Participants are classified in one of four categories: Member Agency, Observer Agency, Liaison, or Associate. Any organization wishing to participate in CCSDS should petition the CCSDS Secretariat in writing requesting permission to participate in one of the four categories. In the case of an application for Member Agency, Observer Agency, or Liaison status, the CCSDS Secretariat will present each request to the CMC (CCSDS Management Council) for consideration and approval. Following the CMC decision, the Secretariat will notify the applicant of the result.
Private companies or institutions should complete an Associate application form. In the case of a request for CCSDS Associate status, the organization is approved once the application has been
  • completed by the applicant;
  • approved by the Principal Delegate of the sponsoring Member or Observer Agency;
  • and signed by the CCSDS Secretariat.

► What rules or requirements does CCSDS have for working group participation?
For details, refer to our Organization and Processes Manual of CCSDS procedures. Some highlights are:
  • We are a consensus organization. Decisions and directions are developed by consensus within the technical and management teams.
  • We have a CCSDS Code of Conduct to promote professional behavior by our participants. This code is available in ANNEX F of our Organization and Processes Manual.
  • We have a patent policy for technology introduced in the standards process. This policy is available in section 2.4.1 of our Organization and Processes Manual.

► Can private companies and institutions participate in CCSDS?
CCSDS recognizes the need for closer ties between private companies/institutions and international space agencies. The CCSDS Associate category allows companies and institutions to participate in the development of CCSDS Recommendations in an attempt to promote a symbiotic relationship that benefits both the private sector and space agencies. Private companies and institutions have developed many CCSDS-compliant, mission-support products, ranging from spacecraft platforms and space-qualified hardware components to ground support hardware and software. Click Here for details.
CCSDS Associate status is obtained by completing the Application Form for CCSDS Associate and obtaining an endorsement from a CCSDS member agency.
Sponsoring CCSDS agencies are responsible for notifying associates whenever new or revised CCSDS Recommendations are posted for review. Associates are encouraged to submit comments about and suggest changes to CCSDS Draft Recommendations. Associate review comments are considered in formulating the formal agency positions on the review document.
There is no charge to CCSDS Associates for their participation.
