Orographic wave drag modelling

The main topic of this article is wave propagation in disordered media. Of particular interest is the long wave regime where an arbitrary rapidly varying orography is modelled as a (stochastic) disordered medium. A brief description of mathematical theory and results is presented. The apparent diffusive behaviour, predicted in the theory for the wave-orography interaction, is confirmed through ...

Differential Drag Spacecraft Rendezvous Using an Adaptive Lyapunov Control Strategy

This paper introduces a novel Lyapunov-based adaptive control strategy for spacecraft maneuvers using atmospheric differential drag. The control forces required for rendezvous maneuvers at low Earth orbits can be generated by varying the aerodynamic drag affecting each spacecraft. This can be accomplished, for example, by rotating dedicated sets of drag panels. Thus, the relative spacecraft mot...

Modelling of spacecraft spin period during eclipse

The majority of scientific satellites investigating the Earth magnetosphere are spin stabilized. The attitude information comes usually from a sun sensor and is missing in the umbra; hence, the accurate experimental determination of vector quantities is not possible during eclipses. The spin period of the spacecraft is generally not constant during these times because the moment of inertia chan...

Guidance and Control for Spacecraft Planar Re-Phasing via Input-Shaping and Differential Drag

This paper proposes a solution to the problem of re-phasing circular or low eccentricity orbiting, short-distance spacecraft, by integrating existing analytical guidance solutions based on input-shaping and analytical control techniques for differential drag based on Lyapunov theory. The combined guidance and control approach is validated via numerical simulations in a full nonlinear environmen...

Chaotic pitch Motion of a Magnetic Spacecraft with viscous Drag in an elliptical Polar Orbit

We study the pitch attitude dynamics of an asymmetric magnetic spacecraft in an almost circular orbit under the influence of a gravity gradient torque. The spacecraft is also subject to the influence of three perturbations: the small eccentricity of the elliptical orbit, a small magnetic torque due to the interaction with the Earth’s magnetic field, and a small aerodynamic viscous drag generate...
