This publication develops a dynamical version of the orbital movement of Lorentz spacecraft in either unperturbed and J2-perturbed environments. It explicitly discusses 3 forms of usual area missions regarding relative orbital keep watch over: spacecraft soaring, rendezvous, and formation flying. thus, it places ahead designs for either open-loop and closed-loop keep watch over schemes propelled or augmented by means of the geomagnetic Lorentz strength. those regulate schemes are solely novel and signify a considerably departure from prior approaches.

Offers the more moderen box of chaos in nonlinear dynamics as a normal extension of classical mechanics as taken care of by means of differential equations. Employs Hamiltonian structures because the hyperlink among classical and nonlinear dynamics, emphasizing the concept that of integrability. additionally discusses nonintegrable dynamics, the basic KAM theorem, integrable partial differential equations, and soliton dynamics.
