ECSS-E-ST-20C – Electrical and electronic (31 July 2008)

This standard has been superseded by ECSS-E-ST-20C Rev.1 (15 October 2019)


This Standard establishes the basic rules and general principles applicable to the electrical, electronic, electromagnetic, microwave and engineering processes. It specifies the tasks of these engineering processes and the basic performance and design requirements in each discipline.

It defines the terminology for the activities within these areas.

It defines the specific requirements for electrical subsystems and payloads, deriving from the system engineering requirements laid out in ECSS-E-ST-10 “Space engineering – System engineering general requirements”.

This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.
