The Coupled Orbit-Attitude Dynamics and Control of Electric Sail in Displaced Solar Orbits [PDF]
International Journal of Aerospace Engineering, 2017 Displaced solar orbits for spacecraft propelled by electric sails are investigated. Since the propulsive thrust is induced by the sail attitude, the orbital and attitude dynamics of electric-sail-based spacecraft are coupled and required to be ...

Orbit Dynamics and Kinematics with Full Quaternions [PDF]
IFAC Proceedings Volumes, 2004 Abstract Full quaternions constitute a compact notation for describing the motion of a body in the space. An important result about full quaternions is that they can be partitioned into a unit quaternion (which describes the orientation with respect to a suitable reference), and a modulus (which represents the translational motion along the direction

Coupled attitude-orbit dynamics and control for an electric sail in a heliocentric transfer mission. [PDF]
PLoS One, 2015 The paper discusses the coupled attitude-orbit dynamics and control of an electric-sail-based spacecraft in a heliocentric transfer mission. The mathematical model characterizing the propulsive thrust is first described as a function of the orbital ...
