[Sls-rfm] [SLS-CC] Fw: SLS coordination - Fw: Clarification on CMC Action

Tue Oct 20 10:05:50 UTC 2020

Dear Massimo,

concerning the RFM WG, I believe that the statement

•CCSDS 401.0-B modulation recommendations should support high-rate uplinks 
and cross links with ranging

is covered by the current RFM charter already. As said in the past, the 
RFM WG is contribution driven and so far we only managed to get one 
proposal with a very draft recommendation for the 22 GHz band.

The proposal is raising a number of actions for the next meeting.

Regards, Enrico

Dear all, 

we have received the following request from CMC, to basically discuss the 
so-called Alacamada input from NASA. 
I believe that nothing has changed since Spring, where it was decided to 
postpone until a face-to-face meeting, but the request is here 
nevertheless. 
I propose to discuss it at the end of our agenda, as time allows. 

Best regards, 
Massimo

Dear Gippo,

My apologies for the tardy reply. The CMC failed to reach a consensus 
decision in the handling of 131.3-P-1.1 and is requesting that the Space 
Link Coding WG and SLS Area consider the ALACAMAD approach presented by 
NASA in the attached presentation and report the WG and Area’s opinion of 
the approach. No doubt this report will be discussed by the CESG before it 
is presented to the CMC.

To be clear, the CMC is not directing you to adopt the ALACAMAD approach, 
but to address whether this approach is implementable, feasible, 
acceptable, etc. Not being involved in the technical discussion myself, I 
would ask that you direct any questions about the proposed ALACAMAD 
approach to Wallace Tai and Peter Shames.

Best regards,

Michael, 
      missing the requested clarification on CMC Action by the end of this 
week, SLS Area cannot ensure any proper reaction in time for reporting. 
Regards
