[SLS-CC] S-Band proximity-1 - CCSDS progress meeting (RFM/CS/SLP)

Wed Jul 24 12:16:32 UTC 2024

Hi all,
Thanks again for attending yesterday meeting, and apologies again for having to leave earlier than meeting closure.

I have uploaded the presentations at https://tinyurl.com/CCSDSJuly2024, and prepared the draft MoM in attachment.
If you could please review them by 1st August 2024 and let me know in case of comments.

Overall, let me say that I was satisfied of having an intermediate meeting.
Although it was simple and short, with constraints due to timezone and vacation periods, we managed to close a number of AIs rather than wait Fall 2024.
If you have any suggestion for improvements, please let me know, and at Fall 2024 we can decide if having a Winter progress meeting in the same spirit.

Intermediate progress meeting of RFM/CS/SLP WGs for S-Band proximity-1

For the meeting organization, I propose a simplified version that I hope will better work for the teleconference:

  *   We review the list of AIs reported below, giving (on average) 15 mins per AI
  *   For each item, the actionee can either:
     *   Provide a full input (as in normal meetings), or
     *   Give the status of the AI (even verbally is fine), for discussing possible open points, doing brainstorming, or simply give a planning for the AI closure
  *   Inputs shall not be announced and provided in advance, unless you want the WG to take a look beforehand
  *   Just in case you believe your AI discussion should take more than 15 mins, please let me know a couple of days before, for adapting the planning

AI_24_04
ESA to check with LPF if possible to provide block diagram information of heterodyning of RF chain and oscillators specs for transmitter and receiver.

Given this information, NASA to reiterate analysis for total phase.
