Full title and description
ISO 21442:2022 — Space systems — General requirements for control engineering. This International Standard establishes high-level, project‑level requirements and principles for control engineering applied across space systems, covering the space segment, ground segment and launch service segment and addressing the full control‑system lifecycle from requirements through disposal.
Abstract
ISO 21442:2022 provides general principles and requirements for technical activities of space control engineering including management, requirements definition, analysis, design, production, verification and validation, operation, maintenance and disposal. The document is intended to be tailored to the specific needs of each space programme and to support consistent refinement and management of control system realizations, including projects with multiple control systems.
General information
- Status: Published.
- Publication date: May 2022.
- Publisher: International Organization for Standardization (ISO).
- ICS / categories: 49.140 (Space systems).
- Edition / version: Edition 1 (2022).
- Number of pages: 34 pages.
Scope
The standard applies to control systems developed as part of a space project and is applicable to all elements that implement control‑functionality: the on‑board (space) segment, ground systems and launch service segment. It defines requirements and guidance for the complete lifecycle of control engineering activities (requirements, analysis, design, production, verification/validation, operations, maintenance and disposal) and supports tailoring to project‑specific needs.
Key topics and requirements
- Control engineering lifecycle: definition of tasks, responsibilities and interfaces across project phases.
- Requirements engineering: capture, allocation and traceability of control system requirements.
- System analysis and design: modeling, performance/robustness considerations and control algorithms.
- Production and integration: implementation, configuration and transfer activities for control elements.
- Verification and validation: test strategies, performance verification and conformity assessment for control functions.
- Operations, maintenance and disposal: operational requirements, sustaining engineering and end‑of‑life considerations.
- Tailoring and project applicability: how to adapt the standard to specific mission profiles and multiple control systems.
Typical use and users
Primary users are space system integrators, control systems engineers (including AOCS engineers), spacecraft and ground‑segment developers, project managers, verification and validation teams, product assurance staff and space agencies. The standard is used to define contractual requirements, guide engineering processes, and support reviews and audits across space projects.
Related standards
ISO 21442 is closely related to other space control engineering and space‑system standards and handbooks. Notable related documents include ECSS control engineering documents (ECSS E‑60 discipline and related control performance and handbook documents such as ECSS‑E‑ST‑60‑10C and E‑HB‑60A), and national/regional technical reports and handbooks that provide complementary guidance for lifecycle tasks and control performance. Practitioners often use ECSS materials together with ISO 21442 when working on European projects.

FAQ
Q: What is this standard?
A: ISO 21442:2022 is an international standard that establishes general requirements and principles for control engineering in space projects, covering the full lifecycle of control systems for space, ground and launch segments.
Q: What does it cover?
A: It covers control engineering management, requirements definition and allocation, analysis and design, production and integration, verification and validation, operation, maintenance and disposal, and guidance on tailoring requirements to specific project contexts.
Q: Who typically uses it?
A: Space agencies, prime contractors, subsystem and payload developers, control/AOCS engineers, test and verification teams, product assurance and project managers use the standard to define engineering processes, contract requirements and verification approaches.
Q: Is it current or superseded?
A: As published in May 2022, ISO 21442:2022 is a current International Standard (Edition 1). Users should check for any later amendments or revisions from ISO or national adoption bodies for the most up‑to‑date status.
Q: Is it part of a series?
A: ISO 21442 sits within ISO’s space systems work and complements other international and regional space engineering standards and handbooks (for example ECSS control engineering documents). It is not a numbered "part" in a multi‑part ISO series but is related by topic to numerous ECSS and ISO space system standards.
