Overview
ISO 13537:2010 - Reference architecture for space data systems (RASDS) provides a standardized, high-level framework for describing space data system architectures. Originally produced by CCSDS (CCSDS 311.0‑M‑1) and adopted by ISO, the RASDS defines a common vocabulary, viewpoints and structure to document architectures for space missions, ground systems and data infrastructures. It is aligned with modern system and software architecture practice and is specifically adapted to the space domain. The standard does not prescribe a specific modeling language or tool, but can be applied with UML, SysML or other modeling approaches.
Key topics and technical requirements
- Standardized architecture approach: Defines how to describe system architectures and high‑level designs to improve clarity and interoperability across agencies and suppliers.
- Viewpoint-driven decomposition: Formalizes multiple viewpoints for architecture description, including:
- Enterprise Viewpoint (mission goals, stakeholders, operational concepts)
- Functional Viewpoint (functions, services and processing elements)
- Connectivity Viewpoint (nodes, links and topology)
- Communications Viewpoint (protocol entities and interfaces)
- Information Viewpoint (data models, information flows)
- Correspondences between viewpoints to ensure consistency across views
- Object characteristics and graphical representations: Guidance on how to represent and characterize architecture elements to support clear documentation.
- Security considerations: Mandatory security section covering relevant issues for each viewpoint.
- Adaptability: Can be implemented using UML/SysML or other modeling notations - the standard remains tool‑agnostic.
Practical applications
- Create consistent, reusable architecture descriptions for spacecraft, ground segments, payload data systems and cross‑agency systems.
- Enable system-of-systems interoperability and clearer procurement specifications by using a commonly understood architecture reference.
- Support design reviews, mission concept studies, interface definition and integration planning with consistent viewpoints and correspondences.
- Facilitate communication between mission architects, software engineers, communications engineers and systems integrators.
Who should use this standard
- CCSDS working groups and space agencies seeking harmonized architecture guidance.
- Mission and project design teams (systems engineers, mission architects).
- Software and system architects, integrators and prime contractors working on space data and information transfer systems.
- Ground segment and payload teams defining interfaces, protocols and data flows.

- ISO/IEC 19793 (Use of UML for ODP System Specifications) - applicable when using UML/SysML with RASDS.
