  • Dynamical aspects of multi-round horseshoe-shaped homoclinic orbits in the RTBP 

    Ollé Torner, Mercè; Barrabés Vera, Esther (2009-11)
    Article
    Restricted access - publisher's policy
    We consider the planar restricted three-body problem and the collinear equilibrium point L3, as an example of a center×saddle equilibrium point in a Hamiltonian with two degrees of freedom.We explore numerically the ...
  • Efficient Two-Body Approximations of Impulsive Transfers between Halo Orbits 

    Fantino, Elena; Flores Le Roux, Roberto Maurice; Al-Khateeb, Ashraf (International Astronautical Federation, 2018)
    Conference report
    Restricted access - publisher's policy
    This contribution presents an efficient method to compute direct transfers between Halo orbits from two circular restricted three-body problems. Owing to the remarkable impulse given over the past two decades to the plans ...
  • Low‐cost trajectories using dynamical systems 

    Cors Iglesias, Josep Maria; Barrabés Vera, Esther (Escola Politècnica Superior d’Enginyeria de Manresa, 2010-12-02)
    Conference lecture
    Open Access
  • Mecánica orbital para un viaje interestelar utilizando velas solares 

    Rocas Alonso, Marc; Mendez Heredero, Adrià (Universitat Politècnica de Catalunya, 2016-07-14)
    Bachelor thesis
    Open Access
    Es sabido que el espacio es y será objeto de estudios e investigaciones para responder algunas de las preguntas más antiguas de la humanidad. El propósito inicial del trabajo surgió del planteamiento sobre la viabilidad ...
  • On dynamics and bifurcations of area-preserving maps with homoclinic tangencies 

    Delshams Valdés, Amadeu; Gonchenko, Marina; Gonchenko, Sergey V. (2015-09-01)
    Article
    Open Access
    We study bifurcations of area-preserving maps, both orientable (symplectic) and non-orientable, with quadratic homoclinic tangencies. We consider one and two parameter general unfoldings and establish results related to ...
  • On the solution of Lambert's problem by regularization 

    Torre Sangrà, David de la; Flores Le Roux, Roberto Maurice; Fantino, Elena (2018-12)
    Article
    Restricted access - publisher's policy
    Lambert's problem is the two-point boundary-value problem resulting from a two-body orbital transfer between two position vectors in a given time. It lies at the very heart of several fundamental astrodynamics and space ...
  • Precessing models and eventual links with galaxy warps 

    Barajas Pichardo, Daniel (Universitat Politècnica de Catalunya, 2010-11)
    Master thesis
    Open Access
    The Restricted Three Body problem is a basic model in celestial mechanics and it has been extensively used in the design of some spatial missions. Sometimes, the designers of these missions consider other similar models ...
  • Proximity maneuvering of libration point orbit formations using adapted finite element methods 

    García Taberner, Laura (Universitat Politècnica de Catalunya, 2010-02-04)
    Doctoral thesis
    Open Access
    This doctoral dissertation is structured in four chapters as follows. The first chapter contains a summary of formation flying projects that have been taken into consideration since few years ago. We specially focus on the ...
  • Review of Lambert's problem 

    Torre Sangrà, David de la; Fantino, Elena (2015)
    Conference lecture
    Open Access
    Lambert’s problem is the orbital boundary-value problem constrained by two points and elapsed time. It is one of the most extensively studied problems in celestial mechanics and astrodynamics, and, as such, it has always ...
  • Spacecraft formations reconfiguration using finite element methodology with adaptive remeshing 

    Masdemont Soler, Josep; García Taberner, Laura (2010)
    Conference report
    Open Access
    We present a methodology to compute trajectories for formation °ying recon¯g- uration problems using a methodology based on ¯nite elements: FEFF (Finite Elements for Formation Flying). In this paper we center ourselves ...
