ECSS-P-001A Rev.1 – ECSS – Glossary of terms (11 June 1997)

This Standard has been cancelled and replaced by ECSS-P-001B (14 July 2004).



This document states the objectives, policy, management and documentation architecture for the establishment of a coherent set of standards for space application, created through the European Cooperation for Space Standardization (ECSS system).

It further defines the process of establishing, implementing, maintaining and withdrawal of this set of standards referred to as ECSS Standards.

ECSS Standards covered by this document may be prepared for space projects and applications, within the following categories:

  • project management requirements;
  • requirements for design, development, manufacturing, verification and operational activities applied to space systems and their constituent parts;
  • Product Assurance requirements and methods;
  • interface requirements, for information relating to space systems and activities, transmitted between organizations.

ECSS Standards include specifications, guidelines, manuals, handbooks and procedures. In general, all documents released by ECSS are referred to as standards.


This document, being the top level document in the ECSS system, is applicable to all work and output from this system.

The ECSS Standards shall serve as reference to all categories of space projects and constitute the baseline for managing the various space projects in Europe.

The standards shall be tailorable to different project requirements and apply to all phases and activities from start to finish of a project, including mission analy-sis and disposal. They are intended to be applied, as relevant, to any party participating in any element of any space mission.
