Space systems — Ground support equipment for use at launch, landing or retrieval sites — General requirements
This document specifies the general characteristics, performance, design, test, checkout, maintenance, safety, reliability, maintainability and quality requirements for ground support equipment (GSE) and systems intended for use at launch, landing or retrieval-site installations, or other locations that are the responsibility of the launch, landing and retrieval site. This document does not specify how to design, checkout and maintain GSE, but establishes the minimum requirements to provide simple, robust, safe, reliable, maintainable and cost-effective GSE. This document is applicable to the design, checkout and maintenance of non-flight hardware and software used to support the operations of transporting, receiving, handling, assembly, inspection, test, checkout, service, launch and recovery of space vehicles and payloads at the launch, landing or retrieval sites. As such, the requirements of this document are optional for hardware used only at the manufacturing, development or test sites prior to arrival at the launch, landing or retrieval sites. However, if such GSE is dual use equipment to be also at a launch, landing or retrieval site, for whatever reason, all the safety-related requirements of this document apply to the GSE.

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.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles,
Subcommittee SC 14, Space systems and operations.
This third edition cancels and replaces the second edition (ISO 14625:2007), which has been technically
revised.
The main changes are as follows:
— requirements related to GSE checkout and maintenance have been added.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
This document is intended to be used when designing new ground support equipment (GSE) that
support space system (launch vehicle or payload) programmes or projects. Existing programmes
and projects can use this document as far as is practical in accordance with sound management and
engineering practices.
This document is applicable at the time the decision is taken to design, construct, manufacture or
procure a given GSE that remains applicable for the useful life of the hardware. However, if modifications
are made to existing hardware, the edition of this document available at the time the modification is
applicable.
When this document is used in procurement, it is advisable that it be reviewed by the programme/
project office for applicability, and that only the clauses that apply to the project or programme be
included in the procurement documentation.
This document can also be used as a template for the development of specific programme or project
GSE specifications or standards.
