Unformatted text preview: as developed by consolidating
the specifications regarding synchronization and channel coding in older CCSDS
Recommended Standards (references [E2] and [E3]).
This Recommended Standard does not change the major technical contents defined in
references [E2] and [E3], but the presentation of the specification has been changed so that:
a) these schemes can be used to transfer any data over any space link in either direction;
b) all CCSDS space link protocols are specified in a unified manner;
c) the layered model matches the Open Systems Interconnection (OSI) Basic Reference
Model (reference ).
Together with the change in presentation, a few technical specifications in references [E2] and
[E3] have been changed in order to define all Space Data Link Protocols in a unified way.
Also, some technical terms in references [E2] and [E3] have been changed in order to unify the
terminology used in all the CCSDS Recommended Standards that define space link protocols
and to define these schemes as general communications schemes. These changes are listed in
annex H of this Recommended Standard.
Through the process of normal evolution, it is expected that expansion, deletion, or
modification of this document may occur. This Recommended Standard is therefore subject
to CCSDS document management and change control procedures, which are defined in the
Procedures Manual for the Consultative Committee for Space Data Systems. Current
versions of CCSDS documents are maintained at the CCSDS Web site:
