Hi Gippo,

Thanks for the feedback.  I purposely shifted this meeting as late as I could to avoid other working meetings.  Now it seems that other Areas WG did the same and we have this unfortunate mash-up.  Shifting earlier does not seem like it will work either, so it may have to be later, after the CESG, which will be unfortunate.  That said, I think it is more important to get the feedback on what we are doing than it is to push ahead with a lightly attended meeting just to meet a schedule.

The other point you made, about meeting with each group separately, is just too much of a burden for my small WG.  My preferred approach is to present this whole approach once, to everyone at once, and then deal with any specific issues that do arise on an area by area basis.

Thanks, Peter

        please note that two out of the three dates you propose are coincident with the SLS Plenary planned for 1st and 2nd June.
I will ask SLSers to check their availability to represent the WGs but I cannot ensure a wide reply and most likely not for today.

Moreover, forgive me for my imprudence but wouldn't be simpler organising bilateral meeting with your WG and each affected WG?
Just my cent...

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 usually 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.

I’d like to schedule this coordination meeting in the week between the end of  the nominal “working meetings” and the CESG /CMC meetings.  That would be the week starting 1 June.  Please go to this Doodle poll and indicate your availability.  Please feel free to invite your WG chairs, and whichever other members of your WGs, you think would be willing to participate.

Replies, please, by CoB, Friday, 7 May 2021.

Thanks, Peter
