The method is restricted to circular-to-circular in-plane tangential low-thrust maneuvers and incorporates a coast arc to ensure efficient propellant usage. The solution directly links the satellite maneuvers to the resulting ground track location, allowing for straightforward overflight targeting of a given by: 1.

V., “Study of Electric Propulsion for Manned Mars Missions,” Journal of Spacecraft and Rockets, Vol. 4, April , pp. – Inclination changes are difficult and expend a lot of delta-v that could be saved for other maneuvers. Inclination changes are most efficiently performed at apoapsis, where orbital velocity is at its lowest. In some cases, it's more efficient to transfer the vessel to a further orbit, perform the inclination maneuver, and transfer back.

Get this from a library. A method of efficient inclination changes for low-thrust spacecraft. [Robert Falck; Leon Gefert; NASA Glenn Research Center.]. I am studying low-thrust maneuvers, in particular a change of inclination only.

According to (Ruggiero et al., )[1], if one writes the perturbation force in the Gauss planetary equations in terms of yaw and pitch angles $\alpha$ and $\beta$, the expression for the change in inclination is as follows.

In spaceflight, an orbital maneuver (otherwise known as a burn) is the use of propulsion systems to change the orbit of a spacecraft far from Earth (for example those in orbits around the Sun) an orbital maneuver is called a deep-space maneuver (DSM).

Such a catalogue of B orbits enables an efficient method of identifying regions of possible displaced orbits for potential. Spacecraft propulsion is any method used to accelerate spacecraft and artificial propulsion or in-space propulsion exclusively deals with propulsion systems used in the vacuum of space and should not be confused with launch l methods, both pragmatic and hypothetical, have been developed each having its own drawbacks and advantages.

Orbital inclination change is an orbital maneuver aimed at changing the inclination of an orbiting body's maneuver is also known as an orbital plane change as the plane of the orbit is tipped.

This maneuver requires a change in the orbital velocity vector at the orbital nodes (i.e. the point where the initial and desired orbits intersect, the line of orbital nodes is defined by the. A rocket engine uses stored rocket propellants as the reaction mass for forming a high-speed propulsive jet of fluid, usually high-temperature gas.

Orbital mechanics, also called flight mechanics, is the study of the motions of artificial satellites and space vehicles moving under the influence of forces such as gravity, atmospheric drag, thrust, etc. Orbital mechanics is a modern offshoot of celestial mechanics which is the study of the motions of natural celestial bodies such as the moon and planets.
