Orbits perturbations and application
WebWhile solar gravity is clearly an important force in the dynamic models for all missions, the analyses and applications mentioned previously focus specifically on incorporating the Sun’s perturbing force as part of a design methodology to adjust the orbital characteristics of a spacecraft. 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…
