Formation flying in space borne artificial magnetic dipole field
(2017)
Comunicació de congrés
Accés obertIn this paper, we consider a new dynamical scenario in which a constantly charged spacecraft (follower) moves near a leader spacecraft, which follows a circular Keplerian orbit around the Earth and generates a rotating ... -
Formation of asymmetric arms in barred galaxies
(Oxford University Press, 2023-04-01)
Article
Accés obertWe establish a dynamical mechanism to explain the origin of the asymmetry between the arms observed in some barred disc galaxies, where one of the two arms emanating from the bar ends is very well defined, while the second ... -
From manifolds to Lagrangian coherent structures in galactic bar models
(EDP Sciences, 2018-10-16)
Article
Accés obertWe study the dynamics near the unstable Lagrangian points in galactic bar models using dynamical system tools in order to determine the global morphology of a barred galaxy. We aim at the case of non-autonomous models, in ... -
Further advances on low-energy lunar impact dynamics
(2010-02)
Article
Accés restringit per política de l'editorialWe extend the analysis, started in a previous work [1], concerning the formation of lunar impact craters due to low-energy trajectories. First, we adopt the Circular Restricted Three- Body Problem and consider different ... -
Geometrical analysis of station-keeping strategies about libration point orbits
(American Institute of Aeronautics and Astronautics, 2022-02-14)
Article
Accés restringit per política de l'editorialThroughout the years, different strategies have been proposed for the station-keeping around the libration point orbits. In this paper, a geometrical comparative analysis is performed between different approaches making ... -
Global analysis of direct transfers from lunar orbits to sun-earth libration point regimes
(Springer Nature, 2021-04-01)
Article
Accés obertIn this paper we look forward to obtain a global picture of simple transfer opportunities from Lunar to Sun-Earth libration orbits, useful for a preliminary design of these mission scenarios. Considering the trajectory of ... -
Haar wavelets based approach for quantifying credit portfolio loses
(2011)
Article
Accés restringit per política de l'editorialThis paper proposes a new methodology to compute Value at Risk (VaR) for quantifying losses in credit portfolios. We approximate the cumulative distribution of the loss function by a finite combination of Haar wavelet ... -
High accuracy state and parameter estimation of GEO-stationary satellites using Jet Transport based nonlinear filtering algorithm
(2018)
Text en actes de congrés
Accés restringit per política de l'editorialWe consider the problem of state and parameter estimation for geostationary spacecraft in an accurate and efficient way. For this purpose we implement a Jet Transport Taylor technique in two coordinate representations, ... -
High order dynamical systems approaches for low-thrust station-keeping of libration point orbits
(2022-01-01)
Article
Accés obertWe derive two families of low-thrust station-keeping control procedures based on the dynamical properties of the phase space near libration point orbits. The first family is obtained as the limit of impulsive maneuvers, ... -
High-fidelity trajectory design to flyby near-Earth asteroids using Cubesats
(2019-09-02)
Article
Accés restringit per política de l'editorialFast development of CubeSat technology now enables the first interplanetary missions. The potential application of CubeSats to flyby near-Earth asteroids is explored in this paper in consideration of CubeSats' limited ... -

(2004)
Article
Accés obertIn this paper a method for finding homoclinic and heteroclinic connections between Lyapunov orbits using invariant manifolds in a given energy surface of the planar restricted circular three body problem is developed. Moreover, ... -
Impulsive transfers between lissajous libration point orbits

(UPC, 1995)
Llibre
Accés restringit a la comunitat UPCEl llibre Introducció a la simulació conté les eines i bases fonamentals dels mètodes emprats en la simulació per ordinador. El contingut, lluny de fer presentacions excessivament teòriques, s'organitza de manera adequada ... -
Invariant manifolds of a non-autonomous quasi-bicircular problem computed via the parameterization method
(2017-08-01)
Article
Accés obertThe parameterization method (pm) has been used to compute high-order parameterizations of invariant manifolds of vector fields at fixed points. This paper extends such approach to invariant manifolds of periodically-perturbed ... -
Jet Transport propagation of uncertainties for orbits around the Earth
(2013)
Text en actes de congrés
Accés obertIn this paper we present a tool to study the non-linear propagation of uncertainties for orbits around the Earth. The tool we introduce is known as Jet Transport and allows to propagate full neighborhoods of initial states ... -
