Perturbations
In space and astronautical engineering, perturbations refer to small deviations or disturbances in the motion of a spacecraft or celestial body from its predicted trajectory caused by various factors such as gravitational forces of other celestial bodies, atmospheric drag, solar radiation pressure, and non-spherical shape of celestial bodies. Perturbations can be classified into two types: deterministic and stochastic. Deterministic perturbations are caused by known and predictable forces, while stochastic perturbations are caused by random and unpredictable forces. Perturbation analysis is an important tool used in space mission design and navigation to accurately predict the trajectory of a spacecraft and to make necessary course corrections to ensure mission success.
