It is shown that with aid of small, continuous thrusts, typical of electrical propulsion systems, it is possible to change independently all orbital elements of spacecraft, and thus to proceed slowly from given orbit to any other; for each maneuver there exists equivalent velocity which depends only on initial and final orbital states, and which can be related directly to spacecraft propulsion parameters; practical realization of electrical propulsion depends on development of efficient propulsion units and of light weight power supplies which are considered; examples of orbital maneuvers are given, including close-Earth, far-Earth and lunar orbits.
