Research report
Open AccessAbstract. We study dynamics and bifurcations of two-dimensional reversible maps having non-transversal heteroclinic cycles containing symmetric saddle periodic points. We consider one-parameter families of reversible ... -
An approach to some classical libration point orbit problems by means of artificial intelligence tecniques
(Universitat Politècnica de Catalunya, 2021-11-29)
Master thesis
Open AccessRapid developments in the last decade have demonstrated the potential of new techniques within the Artificial Intelligence (AI) field as an effective approach for different classical problems in the area of astrodynamics. ... -
Analysis of the relative dynamics of a charged spacecraft moving under the influence of a magnetic field
(2018-09-01)
Article
Open AccessWe analyse a dynamical scenario where a constantly charged spacecraft (follower) moves in the vicinity of another one (leader) that follows a circular Keplerian orbit around the Earth and generates a rotating magnetic ... -
Computation of libration point orbits and manifolds using collocation methods
(Universitat Politècnica de Catalunya, 2016-07-13)
Master thesis
Open AccessThis thesis contains a methodology whose aim is to compute trajectories describing natural motion of the phase space in a neighborhood of Libtation points and stable/unstable manifolds which correspond to these orbits in ... -
Confinement of spacecraft swarms in J2-perturbed orbits about the earth
(2014)
Conference report
Open AccessThere have been studies of the reliability of a swarm [3], based on nano-satellites, that give a study for the num- ber of satellites that can be working as a period of time, with good results for a 5-10 anys time ... -

Coorbital periodic orbits in the three body problem
(2003-05)
Article
Open AccessWe consider the dynamics of coorbital motion of two small moons about a large planet which have nearly circular orbits with almost equal radii. These moons avoid collision because they switch orbits during each close ... -
