Thank you, Ken.
Just for precision there is no CESG resolution to be expected.
There will a SLS Resolution (as soon as Gilles and I complete our usual
checks) and then the document will undergo CESG Poll and CMC Poll.
About comments I wonder whether it may be more practical inserting the new
chapter that specifies use of these codes for forward links (ground to
space or space to space) as chapter 13 instead of chapter 9.
This approach - unless somebody is superstitious and scared by number 13
for this addition :o) - would allow huge renumbering of the last four
chapters currently in https://public.ccsds.org/Pubs/131x0b3e1.pdf
Would it work?
I should provide a few more comments in separate mail.
Regards
Gian Paolo

Subject: Update to CCSDS 131.0-B-3 to add ground-to-space and USLP
Dear colleagues,
At today's teleconference, I believe our working group agreed to release
an updated version of CCSDS 131.0-B-3, “TM Synchronization and Channel
Coding”, for agency review, per the attached document. This incorporates
the minor editorial changes we discussed today, and otherwise is identical
to what you’ve seen before. In short, this standardizes the use of USLP
(in addition to the existing TM and AOS space link protocols), and permits
the use of turbo and LDPC codes on ground-to-space and space-to-space
links.
For Tom, I believe you can expect SLS and CESG resolutions to follow
shortly to support these changes. Like usual, the attached document
contains only the pages with changes, for conciseness. The changes are
minor, except for the addition of slightly more than a page of text to
become a new Section 9. Black text is unchanged from the current
publication, and blue text shows changes and additions; there are no
deletions. Only one figure was slightly modified, and my version is
attached in PowerPoint format, though you likely have a version of your
own.
Thanks to all for your support in this project,
-Ken
