Spacecraft formation flying using Lorentz forces [PDF]
, 2007 The Lorentz Augmented Orbit (LAO) concept is an electromagnetic propulsion system without a tether that uses the interaction between an electrostatically charged spacecraft and the Earth's magnetic field to provide a useful thrust. In Low Earth Orbit (LEO), the Lorentz force acting on a charged spacecraft flying relative to Earth's magnetic field ...
