It shall be demonstrated that the AOCS design does not prevent meeting the requirements imposed by the mission and payload constraints.
These constraints can come from payload (e.g. forbidden attitudes, limited mechanical or magnetic disturbances, and sensitivity to environment) or from mission needs (e.g. antenna pointing for communication and operational constraints).
At satellite level, it shall be demonstrated that the AOCS design is compatible with other functional chains for the attitudes and durations.
1 Examples of other functional chains are power, thermal and communications.
2 This is a satellite level requirement. Design modifications, when needed to ensure compatibility, can be performed on any element of the system.
A mapping of AOCS modes into satellite modes shall be described, to clarify all the possible configurations in which the satellite can be in relation with the AOCS.
