Full title and description

ISO 24411:2022 — Space systems — Micro-vibration testing. This International Standard specifies requirements and guidance for the planning and execution of spacecraft-level micro‑vibration tests intended to characterise the micro‑vibration environment produced by internal disturbance sources and its effect on sensitive payloads (earth observation instruments, space telescopes, optical experiments, telecommunications payloads, etc.).

Abstract

This document sets out requirements for implementation of spacecraft‑level micro‑vibration tests for use by test providers (test designers, test engineers) and provides guidance for spacecraft designers and other interested parties. It covers applicability to space systems containing payload equipment sensitive to micro‑vibrations induced by internal on‑orbit disturbance sources.

Scope

ISO 24411:2022 applies to spacecraft‑level micro‑vibration testing intended to characterise the micro‑vibration environment caused by internal disturbance sources on‑orbit and to measure the resulting responses of the spacecraft and payloads. The standard provides a framework for tailoring tests, identifying disturbance sources, performing preliminary analysis, selecting and configuring test equipment (boundary simulation, excitation, sensors, data acquisition), and executing transfer‑function, modal survey and response measurements. It also addresses laboratory environment and background noise requirements, pre‑conditions, safety and recommended test flow and reporting. The objective is to support reproducible, project‑appropriate micro‑vibration verification for payloads sensitive to very low‑level dynamic excitation.

Key topics and requirements

• Definition of spacecraft‑level micro‑vibration test purpose and tailoring to mission/payload needs.
• Identification and characterisation of internal disturbance sources (reaction wheels, cryocoolers, mechanisms, etc.).
• Preliminary analyses and model‑to‑test correlation requirements (transfer functions and modal surveys).
• Test equipment requirements and recommended configurations for boundary simulation, excitation systems and measurement chains.
• Requirements for transfer‑function measurement, modal survey tests and micro‑vibration response measurements.
• Laboratory environment, background noise limits and conditioning required to obtain valid micro‑vibration data.
• Data acquisition, processing and reporting conventions; guidance on acceptance criteria and safety precautions.
• Recommended test flow and sequence (pre‑conditions, configuration control, instrumentation, runs and post‑test verification).

Typical use and users

Primary users are test providers (test houses and laboratories), spacecraft and payload test engineers, systems and payload designers, integrators and verifiers at space agencies and industry contractors. Use cases include qualification and verification of satellite platforms and payloads where on‑orbit micro‑vibration susceptibility could degrade mission performance (high‑resolution imagers, optical instruments, precision pointing payloads, interferometers and sensitive scientific instruments). Research organisations and test facility managers also use the standard to establish consistent micro‑vibration test methods and reporting.

Related standards

ISO 24411 is intended to complement ISO system test guidance such as ISO 15864 (Space systems — General test methods for spacecraft, subsystems and units) and ISO 17566 (Space systems — General test documentation), which address broader test methods and test documentation formats used for space programmes.

Users should also consider applicable ECSS (European Cooperation for Space Standardization) and national standards for environmental and vibration testing (for example ECSS‑E‑ST‑10‑03 series for mechanical and vibration testing and associated ECSS guidance on micro‑vibration).
