CESG E-Poll Identifier:  CESG-P-2012-06-002 
Approval to release CCSDS 131.3-R-1,  CCSDS Space 
Link Protocols over ETSI DVB-S2 Standard (Red 
Book, Issue 1) for CCSDS Agency review
Results of CESG poll beginning 19 June 2012 and ending 3 July 2012:

                  Abstain:  1 (16.67%) (Taylor)
  Approve Unconditionally:  4 (66.67%) (Peccia, Calzolari, Moury, Scott)
  Approve with Conditions:  1 (16.67%) (Shames)
  Disapprove with Comment:  0 (0%)

CONDITIONS/COMMENTS:

      Peter Shames (Approve with 
Conditions):  Sec 1.4 Applicability should state 
that this is applicable only to "near Earth 
Exploration Satellite Services (EESS) payload 
telemetry", as referenced in Sec 1.2 
Purpose.  The first sentence should read "This 
Recommended Standard applies to the creation of 
Agency standards and to future data 
communications over space links between CCSDS 
Agencies in cross-support situations for near 
Earth Exploration Satellite Services (EESS) payload telemetry."

The spec makes normative reference to a number of 
DVB-S2 terms, e.g. DATAFIELD, MODCOD, FECFRAME, 
BBHEADER, that are only defined in the DVB specs 
and are identified in this document only in a 
non-normative annex.  Since understanding these 
terms and their meaning is essential to 
understanding what is being standardized, these 
definitions should be provided in some context, 
perhaps with a diagram similar to figure 2-2.

Somewhere in this document there should be a 
statement to the effect that any specs otherwise 
defined in CCSDS are not bound to the definitions 
on DVB (8QPSK comes to mind), nor that any 
specifications in DVB, such as ACM & VCM, do not 
constrain other competing definitions within CCSDS.

Approval to release CCSDS 882.0-R-1,  Spacecraft 
Onboard Interface Systems—Low–Data-Rate Wireless 
Communications for Spacecraft Monitoring and 
Control (Red Book, Issue 1) for CCSDS Agency review
Results of CESG poll beginning 29 June 2012 and ending 16 July 2012:

                  Abstain:  0 (0%)
  Approve Unconditionally:  4 (80%) (Peccia, Taylor, Calzolari, Scott)
  Approve with Conditions:  1 (20%) (Shames)
  Disapprove with Comment:  0 (0%)

CONDITIONS/COMMENTS:

      Peter Shames (Approve with 
Conditions):  This appears to be a 35 page 
document that contains two sentences of normative 
content, Sec 3.2.1 and 3.2.1.  Everything else 
appears to be explanatory (Green Book) material.

I am no expert in this domain, but it is not 
clear to me why these two normative statements 
should be asserted by CCSDS, even in a 
Recommended Practice document, but I must just not be getting the concept.

Please describe:

1) Why these two specs and not some other?
2) Why is this document of value to CCSDS agencies?
3) Is there any expectation that all, or even 
most, CCSDS agencies would adopt this as their 
standard for this specific purpose?
