ECSS-E-70 Part 1A, SPACE ENGINEERING: GROUND SYSTEMS AND OPERATIONS PART 1 - PRINCIPLES AND REQUIREMENTS (25-APR-2000)., 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 anintegral
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
