[Sls-rfm] ESA RIDs for Agency review of CCSDS 211.1-P-4.2 (Pink Book) Issue 4.2 April 2026

[Richard Morgan-Owen]

Dear Greg,
In your role as CCSDS Review Coordinator for the subject Book, please find attached the ESA RIDs contributing to the current Agency Review of this book, on Proximity-1 Space Link Protocol - Physical Layer.

I cc: here also the following:

  *
The other related review coordinator for information, concerning  the full set of proximity-1 - related books and session control book currently under review, i.e. reviewing books 235.1-r-1, 211.0-p-6.2, 211.1-p-4.2 & 211.2-p-3.2.
  *
The related WG chairs including all 3 concerned WGs (SLS-RFM, SLS-C&S, SLS-SLP)
  *   The related SLS Area Director


Note: we have put the ESA RIDs together into one word file per CCSDS book and I trust that this does not make too much inconvenience.

We look forward to finalising these 4 books together with the other Agencies at CCSDS.

Best regards,

ESA - European Space Agency
