Tesis doctoral de Manuel Sanjurjo Rivo
Self-balanced electrodynamic tethers can be used to de-orbit objects in low earth orbit. The 98%, approximately, of the total space debris is concentrated in 1500 masses over 100 kg. De-orbiting of some of these objects would markedly decrease the debris population. Electrodynamic tethers are able to exert electrodynamic drag at heights where the aerodynamic drag is negligible (e.G. 2000 km). This production of drag is reliable, cheaper than other solutions and permits to deorbit satellites at the end of their lifetime and any other space debris. Electrodynamic tethers do not use fuel to deorbit space debris; quite the opposite, they can recover a significant part of the orbital energy of the debris to be deorbited during the process, if this is an advisable option. These significant part of the orbital energy of the debris to be deorbited during the process, if this is an advisable option. These significant advantages suggest that they are soon likely to play a decisive role in deorbiting. The dynamic instabilities affecting the attitude motion of these devices at inclined orbits have been removed, from a practical point of view, with the self-balanced electrodynamic tether concept.
