In methods of general perturbations, general differential equations, either of motion or of change in the orbital elements, are solved analytically, usually by series expansions. The result is usually expressed in terms of algebraic and trigonometric functions of the orbital elements of the body in question and the perturbing bodies. This can be applied generally to many different sets of conditions, and is not specific to any particular set of gravitating objects. Historically, general pe… WebMar 15, 2024 · The first edition of this book summarized the perturbation theories and control (stationkeeping) algorithms needed to understand the dynamics, stability, and …
