ECSS-E-ST-10 is a European space standard that provides a framework for system engineering processes in space projects. It defines the processes, activities, and tasks that are required to develop and verify space systems, including requirements engineering, system architecture, and system integration. The standard applies to all types of space systems, including satellites, launch vehicles, and ground support equipment. It provides a systematic approach to system engineering, ensuring that all aspects of the project are considered and integrated to achieve the desired system performance and functionality.

• Requirements of System Engineering: The first phase of system engineering is requirements engineering. This involves identifying and documenting the system requirements, including the functional requirements (system requirements) and non-functional requirements (performance, safety, reliability). The standard guides the requirements of Extraction, Analysis, and Management processes.
• System Architecture: The next phase of system engineering is system architecture, where the system design is developed based on the requirements. The standard guides the system architecture processes, including functional allocation, interface definition, and trade studies. It also covers the development of the system design specifications, including the system-level requirements and the system-level performance parameters.
• System Integration: The final phase of system engineering is system integration. This involves integrating the system components and verifying that the system meets the requirements. The standard guides the integration processes, including the integration plan, integration testing, and verification and validation activities. It also covers the configuration management processes, including the management of the system baseline and the control of changes to the system.

In addition to the system engineering processes, ECSS-E-ST-10 also guides the documentation requirements for system engineering. This includes the development of the system engineering plan, the system engineering management plan, and the system engineering documentation.

Overall, ECSS-E-ST-10 provides a comprehensive framework for system engineering in space projects. By following this standard, space organizations can ensure that their systems are designed and verified to meet the required performance and quality standards, resulting in reliable and safe space missions.
