Full title and description

Space systems — Small-auxiliary-spacecraft (SASC)-to-launch-vehicle interface control document. Provides a standardized format and basic rules for writing an interface control document (ICD) when a small auxiliary spacecraft has an interface only with a launch vehicle.

Abstract

ISO 26869:2012 gives small auxiliary spacecraft (SASC) and launch vehicle (LV) organisations basic rules for preparing an interface control document (ICD) and provides a general format for the document’s presentation when the SASC interfaces only with the LV. The standard sets out the information and structure expected in such ICDs to support clear technical, contractual and operational interfaces.

General information

• Status: Published (confirmed in ISO review 2023).
• Publication date: April 2012.
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 49.140 (Space systems and operations).
• Edition / version: Edition 1 (2012).
• Number of pages: 16.

Scope

Defines the format and minimum content for an interface control document between a small auxiliary spacecraft (SASC) and the launch vehicle (LV) when that is the only interface. It is intended to ensure that responsibilities, interface requirements, and verification arrangements are clearly recorded so that the SASC and LV organisations can integrate payload/auxiliary spacecraft safely and predictably.

Key topics and requirements

• Structure and mandatory sections of the SASC-to-LV ICD (document identification, parties, definitions, interface specifications, verification and acceptance criteria).
• Clear definition of mechanical, electrical, functional and data interfaces between SASC and launch vehicle.
• Statement of responsibilities for design, verification, testing, and on‑range operations.
• Requirements for interface drawings, mass and center-of-gravity data, loads and environmental constraints.
• Documentation and configuration control practices to manage changes to the ICD.

Typical use and users

Used by spacecraft and payload systems engineers, mission integrators, launch service providers, procurement and contract teams, and technical authorities responsible for payload-to-launch-vehicle integration, particularly for small satellites, secondary payloads and auxiliary spacecraft projects.

Related standards

Typically referenced alongside other space systems standards and guidelines from ISO/TC 20 (space systems) and national/industry launch integration documents (for example ECSS or specific launch-provider ICD templates). Projects often pair ISO 26869 with standards on spacecraft environment, mechanical interfaces and debris mitigation as appropriate for the mission.

FAQ

Q: What is this standard?

A: ISO 26869:2012 is an International Standard that specifies the format and basic content rules for an interface control document between a small auxiliary spacecraft (SASC) and a launch vehicle (LV).

Q: What does it cover?

A: It covers the structure and minimum content of the SASC-to-LV ICD, including identification, responsibilities, interface specifications (mechanical, electrical, functional), verification and documentation requirements to support safe integration.

Q: Who typically uses it?

A: Spacecraft/payload engineers, launch providers, mission integrators, systems engineers, and contracting or procurement teams involved in integrating small auxiliary spacecraft with launch vehicles.

Q: Is it current or superseded?

A: The edition is ISO 26869:2012 (Edition 1, April 2012). The ISO record shows the standard was reviewed and confirmed in 2023, so this version remains current.

Q: Is it part of a series?

A: It is part of the body of ISO standards for space systems under ISO/TC 20/SC 14; while not a multi-part numbered series itself, it is commonly used together with other ISO and industry standards covering spacecraft interfaces, environment and safety.

Q: What are the key keywords?

A: SASC, interface control document (ICD), launch vehicle, payload integration, spacecraft interface, configuration control, interface requirements.
