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

Tue Aug 29 14:06:12 UTC 2023

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?

Andrea
