Overview
ISO 17689:2023 - Space systems - Interface control documents between ground systems, ground support equipment and launch vehicle with payload - defines basic requirements for writing interface control documents (ICDs) and procedures to manage interfaces in a launch system. The standard addresses ICDs for interfaces between ground support equipment (GSE), payloads, launch vehicles, and the launch site (buildings and utility systems). It is intended for organizations developing GSE and operators performing space activity and supports safe, compatible integration across multi‑party projects.
Key topics and requirements
- Scope of ICDs: Four primary ICD types are covered - GSE↔payload, GSE↔launch vehicle, GSE↔GSE (between items), and GSE↔launch site.
- Minimum ICD content: An item ICD must include a cover sheet, revision record, applicability, description of the interface, and verification requirements.
- Document identification and coding: ICDs use formal reference numbers composed of blocks that identify project, document type, product tree location, version differences, and index numbers to make interface tracking and cross‑referencing systematic.
- Format and presentation: ICDs may be textual, graphical (drawings), or combined; internal ICDs can be used for complex internal GSE interfaces.
- Development process: The standard prescribes a hierarchical ICD structure, distribution of responsibilities, and procedures for ICD development, coordination, verification and validation throughout the launch system lifecycle.
- Limitations: ICD format excludes detailed GSE performance, mechanical environment endurance, and QA provisions, which remain in separate technical specifications.
- Risk and safety focus: ICDs are framed to improve interface compatibility, reduce accidents, and support acceptable risk management during design and operations.
Applications and practical value
- Payload integration and launch readiness: Ensures electrical, mechanical, thermal, hydraulic and pneumatic interfaces are explicitly defined and verifiable prior to integration.
- Multi‑party projects and contracting: Clarifies responsibilities among launch providers, GSE developers and payload customers to avoid interface mismatches.
- Safety and operations: Supports prelaunch planning, change control, and hazard mitigation by formalizing interface requirements and verification steps.
- Configuration management: Enables systematic indexing, revision control and traceability of interfaces across the launch system lifecycle.
Who should use this standard
- GSE designers and manufacturers
- Launch system integrators and operators
- Payload developers and mission integrators
- Interface controllers, systems engineers, safety and verification teams
