Spacecraft and Payload Pointing focuses on development of the
attitude determination and control system (ADACS) for a spacecraft,
including payload pointing. Such systems can require knowledge of a
large diversity of disciplines for two reasons. First, the ADACS
itself is a broad subject, including the dynamics of the spacecraft
and payloads, the physics and engineering of the ADACS sensor and
actuator hardware, control and filtering theory, plus systems
engineering. Second, many disciplines are involved since the ADACS
must interface with several other subsystems (notably payload,
structure, and command and data handling [C&DH]) and because
ADACS performance translates into key mission performance
parameters such as pointing control. When mission requirements are
flowed down to the spacecraft and then to its subsystems, the
engineer must be able to translate these requirements into
appropriate terms at each level.Mission requirements are customer
related (such as the ability to broadcast a TV signal or transmit
data); they must be translated into spacecraft system concepts
(orbits, transmitted power levels), then to subsystem requirements
(available power, antenna gain, antenna pointing accuracy), and
further down to the level of components.Rather than treat each of
the subject areas involved in ADACS design in great depth, this
book aims to show how they fit together. The subject can be
examined from two basic points of view. The first is that of the
systems engineer. This view focuses on requirements, requirements
flowdowns, and verification. In it, the onboard hardware and
software are regarded as black boxes, defined by their functions,
reliability, etc. The other standpoint is that of the physicist or
engineer who focuses on what is involved in actually getting these
items to work. This view includes actions such as quantifying
feasible performance levels, learning how they can be improved, and
understanding their fundamental limitations.
