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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information

Introduction
This International Standard is intended for application at realization of interstate, intergovernmental
or non-governmental space activity, between operators of some country and different organizations on
the basis of their space activity contracts.
Interfaced (connected) devices development by two and more designers (commands, organizations,
developers of other specializations, etс.) creates a need for coordination between them to prevent
interfaces discrepancy for unlimited possibilities of design (construction) perfection during the
creation of space technics.
This International Standard establishes basic requirements for interface control documents (ICD)
writing and interface control procedures for the following items included in launch system: payload,
launch vehicle, ground support equipment (according to ISO 14625:2007) and launch site (buildings
with technical systems). Notably
a) ICD between payload and launch vehicle (according to ISO 15863:2003),
b) ICD between ground support equipment and payload (this International Standard),
c) ICD between ground support equipment and launch vehicle (this International Standard),
d) ICD between items of ground support equipment (this International Standard), and
e) ICD between ground support equipment and launch site (this International Standard).
ICD enables systematic creation (development), operation and management of interfaces b) to e) at
all stages of life cycle of launch system. It is necessary for the purpose of guarantee of launch system
normal functioning, prevention of accident and reduces of acceptable risk at joint space projects and
services of space vehicles insertion into space.
Application of this International Standard at design and development stages will improve control and
compatibility of all interfaces [b) to e)].
Application of this International Standard at operation stage will improve launch system safety and
facilitate control of interfaces.

INTERNATIONAL STANDARD ISO 17689:2015(E)
Space systems — Interface control documents between
ground systems, ground support equipment and launch
vehicle with payload
1 Scope
This International Standard is applied for organizations developing ground support equipment and also
for operators performing space activity.
Interface control documents format defined here does not contain the descriptions regarding various
properties of ground support equipment (i.e. performance, functions or endurance to launch mechanical
environment or quality assurance provisions) which are defined in technical specifications.
Control of interfaces, independently of its frequency or depth, cannot replace stages of parameters
definition of high-quality production and development of technical requirements of project, design and
development. Interfaces control is used as a control process that can provide necessary verification of
successful finishing of design at a stated in contract period.
This International Standard establishes basic requirements for interface control documents (ICD)
writing and interface control procedures for the following items included in launch system: payload,
launch vehicle, ground support equipment (according to ISO 14625:2007) and launch site (buildings
with technical systems). Notably
a) ICD between payload and launch vehicle (according to ISO 15863:2003),
b) ICD between ground support equipment and payload (this International Standard),
c) ICD between ground support equipment and launch vehicle (this International Standard),
d) ICD between items of ground support equipment (this International Standard), and
e) ICD between ground support equipment and launch site (this International Standard).

3 General
3.1 ICD for ground support equipment is developed as separate document for each part included
in launch system: payload, launch vehicle, items of ground support equipment, launch site (building
constructions with technical systems):
a) ICD between ground support equipment and payload (this International Standard);
b) ICD between ground support equipment and launch vehicle (this International Standard);
c) ICD between items of ground support equipment (this International Standard);
d) ICD between ground support equipment and launch site (this International Standard).
The leading enterprise-developer of ground support equipment is responsible for the development of a
list of ICD for this equipment.
The leading enterprise-developer of a launch site supervises types, quantity and location of interfaces
of ground support equipment items which were developed by the enterprises according to ICD for items.
The developers of items of a launch site develop ICD and coordinate them with other enterprises which
are developers of the items which are interfaced.
3.2 The initiative in determination of interfaces design belongs to the enterprise having a ready
(existing) item or element of the device in relation to the enterprises which should develop an interfaced
item or device at participation in the joint project.
The organization which performs launch services of space vehicles gives the full information about
interfaces of launch pad to the organization which orders the launch services.
The payload authorities shall provide interface condition to operator.

3.3 It is necessary to have a note in the technical specification about presence of ICD on item.
Each interface shall have the code which contains the basic information about it.
EXAMPLE ICD XXXX-YYYY-000-ААА – interface code, where
— XXXX is the source item code,
— YYYY is the consumer item code,
— 000 is the interface number, and
— ААА is the code of place where the interface is located.
After interface number, a reference number or code (in brackets) may indicate the drawing (list) where
this interface is figured.
EXAMPLE А110-B010-001-005 (А110.08.03.01).
Number of symbols and use of figures and letters in index should correspond to approved codes in
technical specifications.
3.4 ICD can be drawn in the form of text, in the form of picture (drawing) or in complex (text and
picture) form.
The specific indicator like the letter «G» may be added separately t
