This standards has been cancelled and superseded by ECSS-E-ST-20C (31 July 2008).
This Standard establishes the basic rules and general principles applicable to the electrical, electronic, electromagnetic, microwave and optical 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 the Space System Engineering Standard ECSS-E-10.
When viewed from the perspective of a specific project context, the requirements defined in this Standard should be tailored to match the genuine requirements of a particular profile and circumstances of a project.
NOTE: Tailoring is a process by which individual requirements or specifications, standards and related documents are evaluated and made applicable to a specific project. Application of the contract requirements may necessitate deletion, addition or modification of the requirements of this Standard.
