Oscillation
In space and astronautical engineering, oscillation refers to the repetitive motion of a spacecraft or satellite around its equilibrium position. This motion can be caused by various factors such as disturbances from external forces, internal system dynamics, or control system instability. Oscillations can be classified into different types based on their characteristics such as amplitude, frequency, and damping ratio. Some common types of oscillations in space systems include attitude oscillations, structural oscillations, and orbit oscillations. Attitude oscillations refer to the motion of a spacecraft or satellite around its rotational axis, while structural oscillations refer to the motion of its components or structures. Orbit oscillations refer to the deviation of a spacecraft or satellite from its intended orbit due to perturbations from gravitational or atmospheric forces. Oscillations can have significant impacts on the performance and safety of space systems, and thus, they need to be carefully analyzed and controlled.
