Semi-Analytic Electrodynamic Tether Guidance Using Rotating Dipole Model of Earth;'s Magnetic Field
An electrodynamic tether provides a propellantless means of propulsion for spacecraft in Low Earth Orbit. Several proposed applications of the electrodynamic tether require a general change in the orbit, such as rendezvous for space surveillance or debris mitigation. This paper derives a current control law for electrodynamic tethers to achieve a specific general orbital change using a tilted, rotating dipole model of Earth’s magnetic field. The control law is developed using a modified, semi-analytic derivation of the Gaussian Variation of Parameters equations. The semi-analytic method is used ...
