Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10537 was prepared by the Consultative Committee for Space Data Systems (CCSDS) (as
CCSDS 661.0-B-1, September 2008) and was adopted (without modifications except those stated in Clause 2
of this International Standard) by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee
SC 13, Space data and information transfer systems.

ISO 10537:2010(E)
CCSDS RECOMMENDED STANDARD FOR ENCAPSULATION SERVICE
STATEMENT OF INTENT
The Consultative Committee for Space Data Systems (CCSDS) is an organization officially
established by the management of its members. The Committee meets periodically to address
data systems problems that are common to all participants, and to formulate sound technical
solutions to these problems. Inasmuch as participation in the CCSDS is completely voluntary,
the results of Committee actions are termed Recommended Standards and are not
considered binding on any Agency.
This Recommended Standard is issued by, and represents the consensus of, the CCSDS
members. Endorsement of this Recommendation is entirely voluntary. Endorsement,
however, indicates the following understandings:
o Whenever a member establishes a CCSDS-related standard, this standard will be in
accord with the relevant Recommended Standard. Establishing such a standard
does not preclude other provisions which a member may develop.
o Whenever a member establishes a CCSDS-related standard, that member will
provide other CCSDS members with the following information:
-- The standard itself.
-- The anticipated date of initial operational capability.
-- The anticipated duration of operational service.
o Specific service arrangements shall be made via memoranda of agreement. Neither
this Recommended Standard nor any ensuing standard is a substitute for a
memorandum of agreement.
No later than five years from its date of issuance, this Recommended Standard will be
reviewed by the CCSDS to determine whether it should: (1) remain in effect without change;
(2) be changed to reflect the impact of new technologies, new requirements, or new
directions; or (3) be retired or canceled.
In those instances when a new version of a Recommended Standard is issued, existing
CCSDS-related member standards and implementations are not negated or deemed to be non-
CCSDS compatible. It is the responsibility of each member to determine when such
standards or implementations are to be modified. Each member is, however, strongly
encouraged to direct planning for its new standards and implementations towards the later
version of the Recommended Standard.

CCSDS RECOMMENDED STANDARD FOR ENCAPSULATION SERVICE
FOREWORD
This document is a Recommended Standard for use in developing flight and ground
systems for space missions and has been prepared by the Consultative Committee for Space
Data Systems (CCSDS). The Encapsulation Service described herein is intended for
missions that are cross-supported between Agencies of the CCSDS.
This Recommended Standard specifies a communications service to be used by space
missions to transfer protocol data units that are not directly transferred by the Space Data
Link Protocols (references [1]-[3]) over a ground-to-space or space-to-space communications
link. The data units transferred with this service are encapsulated in either Space Packets,
defined in reference [5], or Encapsulation Packets, defined in this document.
This Recommended Standard is developed from the Encapsulation Service that was defined
in the Advanced Orbiting Systems (AOS) Recommended Standard (reference [B2]). In this
Recommended Standard, that service is re-defined so that it can be used with any of the
Space Data Link Protocols (references [1]-[3]). Also, the Encapsulation Packet that was
defined in references [B2]-[B4] is included in this Recommended Standard as an alternative
packet structure for encapsulation.
In order to define all Space Data Link Protocols in a unified way, a few technical
specifications of the Encapsulation Service in reference [B2] have been changed. Also, some
technical terms in references [B2]-[B4] have been changed in order to unify the terminology
used in all the CCSDS Recommended Standards that define space link protocols. These
changes are listed in annex C of this Recommended Standard .
Through the process of normal evolution, it is expected that expansion, deletion or
modification to this document may occur. This Recommended Standard is therefore subject
to CCSDS document management and change control procedures, as defined in reference
[B1]. Current versions of CCSDS documents are maintained at the CCSDS Web site:
http://www.ccsds.org/
Questions relating to the contents or status of this document should be addressed to the
CCSDS Secretariat at the address indicated on page i.

CCSDS RECOMMENDED STANDARD FOR ENCAPSULATION SERVICE
1 INTRODUCTION
1.1 PURPOSE
The purpose of this Recommended Standard is to specify the Encapsulation Service. This
service is to be used by space missions to transfer data units that are not directly transferred
by the Space Data Link Protocols (references [1]-[4]) over a ground-to-space or space-to-
space communications link.
1.2 SCOPE
This Recommended Standard defines the Encapsulation Service in terms of:
a) the service primitives provided to the users of this service;
b) the protocol data units employed by the service provider; and
c) the procedures performed by the service provider.
It does not specify:
a) individual implementations or products;
b) the implementation of service interfaces within real systems;
c) the methods or technologies required to perform the procedures; or
d) the management activities required to configure and control the service.
1.3 APPLICABILITY
This Recommended Standard applies to the creation of Agency standards and to the future
data communications over space links between CCSDS Agencies in cross-support situations.
The Recommended Standard includes comprehensive specification of the service for inter-
Agency cross support. It is neither a specification of, nor a design for, real systems that may
be implemented for existing or future missions.
The Recommended Standard specified in this document is to be invoked through the normal
standards programs of each CCSDS Agency, and is applicable to those missions for which
cross support based on capabilities described in this Recommended Standard is anticipated.
Where mandatory capabilities are clearly indicated in sections of the Recommended
Standard, they must be implemented when this document is used as a basis for cross support.
Where options are allowed or implied, implementation of these options is subject to specific
bilateral cross support agreements between the Agencies involved.

CCSDS RECOMMENDED STANDARD FOR ENCAPSULATION SERVICE
1.4 RATIONALE
The CCSDS believes it is important to document the rationale underlying the
recommendations chosen, so that future evaluations of proposed changes or improvements
will not lose sight of previous decisions. Concept and rationale behind the decisions that
formed the basis for this Recommended Standard is documented in reference [B5].
1.5 DOCUMENT STRUCTURE
This document is divided into five numbered sections and three annexes:
a) Section 1 presents the purpose, scope, applicability and rationale of this
Recommended Standard and lists the conventions, definitions, and references used
throughout the document;
b) Section 2 provides an overview of the Encapsulation Service;
c) Section 3 defines the service primitives provided for this service;
d) Section 4 specifies the protocol data units and procedures employed by the service
provider;
e) Section 5 lists the managed parameters associated with this service;
f) Annex A lists all acronyms used within this document;
g) Annex B provides a list of informative references;
h) Annex C lists the changes from older CCSDS Recommendations [B2]-[B4].
1.6 CONVENTIONS AND DEFINITIONS
1.6.1 DEFINITIONS
1.6.1.1 Definitions from the Open Systems Interconnection (OSI) Basic Reference
Model

1.6.2 NOMENCLATURE
The following conventions apply throughout this Recommended Standard:
a) the words ‘shall’ and ‘must’ imply a binding and verifiable specification;
b) the word ‘should’ implies an optional, but desirable, specification;
c) the word ‘may’ implies an optional specification;
d) the words ‘is’, ‘are’, and ‘will’ imply statements of fact.
1.6.3 CONVENTIONS
In this document, the following convention is used to identify each bit in an N-bit field. The
first bit in the field to be transmitted (i.e., the most left-justified when drawing a figure) is
defined to be ‘Bit 0’; the following bit is defined to be ‘Bit 1’ and so on up to ‘Bit N-1’.
When the field is used to express a binary value (such as a counter), the Most Significant Bit
(MSB) shall be the first transmitted bit of the field, i.e., ‘Bit 0’ (see figure 1-1).
BIT N-1
BIT 0
N-BIT DATA FIELD
FIRST BIT TRANSMITTED = MSB

Figure 1-1: Bit Numbering Convention
In accordance with standard data-communications practice, data fields are often grouped into
8-bit ‘words’ which conform to the above convention. Throughout this Recommended
Standard, such an 8-bit word is called an ‘octet’.
The numbering for octets within a data structure starts with 0.
By CCSDS convention, all ‘spare’ bits shall be permanently set to value ‘zero’.

CCSDS RECOMMENDED STANDARD FOR ENCAPSULATION SERVICE
2 OVERVIEW
2.1 CONCEPT OF ENCAPSULATION SERVICE
The Encapsulation Service is a data transfer service to be used by space missions to transfer
data units that are not directly transferred by the Space Data Link Protocols (references [1]-[4])
1
over a ground-to-space or space-to-space communications link (hereafter called a space link).
Data units that are directly transferred by the Space Data Link Protocols have a Packet
Version Number (PVN) authorized by CCSDS. (A list of the Packet Version Numbers
presently authorized by CCSDS is contained in reference [8].) The main purpose of the
Encapsulation Service is to provide a mechanism to transfer data units without an authorized
PVN over a s
