Space systems — Requirements of launch vehicle (LV) to electrical ground support equipment (EGSE) interfaces

This document provides requirements for launch system designers or interface designers regarding interfaces between LV and EGSE, which is used to support on-line processing. It defines electrical interface types, design requirements, environment requirements, verification methods (analyses and tests), and interface check operation requirements. This document is intended to minimize design costs and reduce risks from errors resulting from miscommunication. It does not limit LV or EGSE organizational requirements to specify a unique interface.

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

Introduction
This document provides design requirements of electrical interfaces between launch vehicles (LV)
and electrical ground support equipment (EGSE) for launch system or interface designers. The defined
interface type and requirements constitute the LV to EGSE interface control document (ICD).
The purpose of this document is to specify standardized requirements and help the designer specify
the LV to EGSE ICD and subsequently help users to clearly understand the designer’s intentions, and
hence minimize costs and reduce risk from errors resulting from miscommunication. This document
does not consider interface design details and does not limit LV or EGSE organizational requirements to
specify a unique interface.
