ISO 13537:2010 presents a reference architecture for space data systems (RASDS). The RASDS is intended to provide a standardized approach for description of data system architectures and high-level designs, which individual CCSDS working groups may use within CCSDS. This approach is aligned with current practices in the fields of system and software architecture and is specifically adapted for the space domain. While it is intended for use within CCSDS, it is also suitable for use by mission and project design teams to describe system architectures and designs within the space domain. It does not propose any specific formal modeling method or tool, but can be adapted to use methods like UML or SysML.
