scope:

NEN-EN 16603-60-10 deals with control systems developed as part of a space project. It is applicable to all the elements of a space system, including the space segment, the ground segment and the launch service segment. It addresses the issue of control performance, in terms of definition, specification, verification and validation methods and processes. The standard defines a general framework for handling performance indicators, which applies to all disciplines involving control engineering, and which can be applied as well at different levels ranging from equipment to system level. It also focuses on the specific performance indicators applicable to the case of closed-loop control systems - mainly stability and robustness. Rules are provided for combining different error sources in order to build up a performance error budget and use this to assess the compliance with a requirement. This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.
