[CESG] CESG / SAWG Coordination Meeting

Thu May 27 18:09:37 UTC 2021

Dear SLS, CSS, SIS, and SEA colleagues,

In the SEA Systems Architecture WG (SAWG) we are working on a revision of the Space Communication Cross Support Architecture Requirements Document (CCSDS SCCS-ARD, 901.1-M-1).  That document presently describes how more than fifty-seven (57) normative CCSDS standards may be fitted together, like some giant jig-saw puzzle, to mee the needs of users who design and build flight and ground communications assets.  In the time since that standard was published a number of these normative standards have been updated, some with new features, and a significant number of new standards have been published, especially in SLS and CSS, but also in SEA itself.

We have identified some issues with the current document structure that requires changes to the chapters for clarity of presentation.  We have also identified some complexities introduced by new standards, such as USLP, optical comm, VCM, and newer security features that are driving a change in approach.  And we are adding all of the new standards that have been introduced since this document was published.

We would like to present these issues and how we plan to  address them to whichever members of your teams would be willing to participate.  This is  an unusual request for a WG, which typically do this sort of work behind closed doors, but since this document cross cuts all of your WGs we thought it useful and, we hope, valuable to you.  Since we have focused on ABA deployments the only Area that is not directly affected yet is SIS. That said, you may still wish to see what we are doing to the layers that underpin your networking layer standards.

Thanks, Peter
