[CMC Alert] CCSDS Review of CCSDS 131.0-P-1.2, TM Synchronization and Channel Coding

[CCSDS Rapporteur]

Control Number: RP 11-03

The following draft CCSDS Recommended Standard has been placed on 
line for CCSDS Agency review:

      CCSDS 131.0-P-1.2.  TM Synchronization and Channel Coding.
                          Pink Book.  February 2011.

DOCUMENT DESCRIPTION:  The Recommended Standard for TM 
Synchronization and Channel Coding contains specifications to be used 
by space missions on synchronous communications links.  Changes from 
the previous draft are indicated in the document as follows:

Text where technical material has been rephrased for clarification is 
marked with change bars in the right margin.  Changes to the 
technical specification are marked with insert/strikethrough notation 
as well as with change bars in the right margin.

Several changes affecting the appearance of the document have been 
made and are not individually marked:

- the document has been reorganized for uniformity of presentation;
- specifications have been rephrased in CCSDS terse style, using 
"shall" to specify binding and verifiable requirements, and 
non-normative text has been differentiated from normative text (see 1.6.2);
- the terms "Codeblock" and "Codeword" have been clearly 
differentiated, with use of the term "Codeblock" confined to 
Reed-Solomon coding (see definitions in annex D);
- references to optimization of LDPC codes for near-Earth and deep 
space have been changed to explicit code-length references;
- the security section (formerly section 11) has been moved to an 
informative annex.
