ECSS-E-70 Part 1A Ground systems and operations – Part 1: Principles and requirements (25 April 2000)

This Standard, together with ECSS-E-70 Part 2A (24 April 2000), has been cancelled and its content in now covered by ECSS-E-ST-70C (31 July 2008).

Scope

Within the frame of the overall engineering standards for space missions, this Standard contains the basic rules, principles and requirements to be applied to the engineering of the ground segment and mission operations, which form an integral part of the overall system implementing a space mission.

This Standard includes development of ground segment, operations preparation activities, mission planning activities, mission evaluation activities, the conduct of operations proper, and all post-operational activities. The ground segment comprises the ground systems (i.e. all ground facilities, hardware and software) and all operational aspects such as personnel and related data repositories required on ground to perform mission operations.

For reasons of recognized commonality, ground segment within the meaning of this Standard includes those elements and facilities required for the purpose of implementing the mission and fulfilling the missions requirements while the relevant space segments are in-orbit. It covers ground elements used for purposes of assembly, integration and verification of the space segment, to the extent needed for ground segment end-to-end verification activities. It also covers elements integrated into the ground segment after completion of space segment AIT; space segment AIT proper being considered outside the scope of this Standard.

It does not however cover the spacecraft activities and facilities interfacing the launch service segment. Furthermore, while this Standard is applicable to all classes of missions it does not consider aspects that are specific to manned space missions.

This Standard is structured as follows:

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 of specifications, standards and related documents are evaluated, and made applicable to a specific project by selection, and in some exceptional cases, modification of existing or addition of new requirements.
