European Foreword
This document (EN 16603-50-21:2022) has been prepared by Technical Committee CEN-
CENELEC/TC 5 “Space”, the secretariat of which is held by DIN.
This standard (EN 16603-50-21:2022) originates from ECSS-E-AS-50-21C.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by January 2023, and conflicting national standards shall
be withdrawn at the latest by January 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 16603-50-01:2014.
The main changes with respect to EN 16603-50-01:2014 are listed below:
- Replacement of the Standard by an Adoption Notice.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association.
This document has been developed to cover specifically space systems and has therefore precedence
over any EN covering the same scope but with a wider domain of applicability (e.g. : aerospace).
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of
Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia,
Spain, Sweden, Switzerland, Turkey and the United Kingdom.
Scope
This document identifies the clauses and requirements modified with respect to
the standard CCSDS 131.0-B-3, TM Synchronization and Channel Coding, Issue 3,
September 2017 for application in ECSS.

Context information
The standard CCSDS 131.0-B-3, TM Synchronization and Channel Coding, has
been developed by CCSDS for use in developing synchronization and channel
coding systems.
With this Adoption Notice ECSS is adopting and applying CCSDS 131.0-B-3
with a minimum set of modifications, identified in the present document, to
allow for reference and for a consistent integration in the ECSS system of
standards.
CCSDS 131.0-B-3 is similar to the EN 16603-50-01 (based on ECSS-E-ST-50-01)
Space data links - Telemetry synchronization and channel codin.
EN 16603-50-01 (based on ECSS-E-ST-50-01) is superseded by EN 16603-50-21
(based on ECSS-E-AS-50-21).
Differences between these standards that are not covered by the normative
modifications in clause 4 are described in the informative Annex A.
