[SLS-CC] [EXTERNAL] AI_23_04 - S-Band Proximity-1 Extension

Thu Sep 21 09:03:16 UTC 2023

FYI that Wing/NASA spotted that we forgot to include the "uncoded" case in the Modcod list (slide 4 & 5).
I added a proposal, and included a sentence as "Final MODCOD numbering can be agreed at Fall 2023 meeting" for giving you the flexibility to discuss this further in The Hague.

If there are no additional comments, I will formalize the input on Monday

Thanks Ken,
Indeed I mixed rates. Also spotted on Slide 5 the "not currently foreseen" has to refer to the 4/5

Andrea,

This is just a correction of a minor typographical error: on slide 4, I think MODCODs 022 and 122 are intended to refer to LDPC 2/3, not LDPC 3/4.

Dear WG,
Thanks for your patience. The busy period took me longer than expected in doing the merge.

I let you know that I received comments from Jorge/ESA, Wing/NASA, and Shannon/NASA, and harmonized them in a unified C&S presentation, that can be provided as input to SLP WG, in preparation to Fall meetings (see attachment).

Please let me know if you should have any residual comment by 20 September, EOB (it is a very short presentation, 4 slides).
If there are no objections, then on 21st, I will send it formally to Greg on behalf of C&S, and record it as input SLS-CS_23-08 for joint meetings.

Dear WG,
I hope this finds you well and you had a nice summer break.

As part of AI_23_04, the WGs, including C&S, had the AI to
a) provide comments to SLP about the Proximity-1 directives, and
b) provide a list of Modcod assignments to SLP
Being the AI quite simple, but at the same time fundamental for SLP activities, I was wondering if we can sort it out by email well before Fall 2023.

In this respect, you find in attachment:
-for sub-action a), the following docs prepared by Greg/NASA,
Lunar Prox1 Directives: the set of directives for Lunar Ops
Proximity Session Access Control Parameters: defining the default set of Prox-1 parameters across Physical and Link layers
-for sub-action b), the following doc prepared by Nicola/ESA,
               MODCOD number: a preliminary list of possible modcods, based on the Spring 2023 agreements

Could you provide your comments (only to me) by 8th September EOB? Then, I will do a merge, distribute back to the WG, and re-iterate with Greg.

Good to hear from you Andrea,

What you attached is the SLP WG white paper on the overall Prox-1 Lunar work.
I've split that problem into two different CCSDS Projects in the SLP WG and included the attachments.
Project 1 is about providing a set of Prox-1 directives for Lunar ops. The one you are talking about.
Project 2 is defining the default set of Prox-1 parameters across Physical and Link layers that will be documented in a Prox-1 SDLP Annex. I've attached that file as well - "Prox-1 Session Access Control".

Looking forward to working with the C&S WG on these projects,
Greg

Hi Greg,
For Fall 2023, our WG had AI to provide you with comments about the new Proxy-1 directive, and provide then to you a list of Modcods to be included.

I have the one in attachment, dated April 2023. Maybe you have already a newer update that I can share with the WG?
