Attitude is the three-dimensional orientation of a vehicle with respect to a specified reference frame. Attitude systems include the sensors, actuators, avionics, algorithms, software, and ground support equipment used to determine and control the attitude of a vehicle.
Passive control techniques take advantage of basic physical principles and/or naturally occurring forces by designing the spacecraft so as to enhance the effect of one force, while reducing the effect of others. Active Control Systems directly sense spacecraft attitude and supply a torque command to alter it as required.
Fundamentals of Spacecraft Attitude Control | NESC Academy …
Aug 16, 2024 · Spacecraft attitude control systems are onboard systems that autonomously orient a spacecraft relative to a target reference frame. Spacecraft operate in a regime of very little disturbance torque as compared to atmospheric vehicles, and we therefore have greater expectations for their accuracy and stability.
Virtually all spacecraft payloads and subsystems rely on closed-loop systems to control • Imaging, communicating, and operating other missions—payloads • Momentum (angular and linear)—attitude and orbit control subsystems (AOCS)
