      El objetivo principal de este proyecto es diseñar un prototipo de vela solar que se pueda utilizar para hacer un viaje al espacio exterior, o científicamente llamado Viaje interestelar. Este es un estudio únicamente para ...
    • 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 ...
    • Early Results from the DISCOVERER Project 

      Roberts, Peter C.E; Crisp, Nicholas H.; Oiko, Vitor; Edmonson, Steve; Romano, Francesco; Rodríguez Donaire, Silvia; García-Almiñana, Daniel; Haigh, Sarah J.; Holmes, Brandon E.A.; Livadiotti, Sabrina; Sureda Anfres, Miquel (International Astronautical Federation, 2021)
      Conference report
      Restricted access - publisher's policy
      The use of very low Earth orbits (VLEO), for communications and remote sensing satellites, offers a number of significant payload and platform benefits. Imaging from these altitudes allows higher resolution or smaller ...
    • 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 ...
    • Mission analysis for a swarm of femtosatellites to study the lower thermosphere 

      Aidynbay, Nurmakhan (Universitat Politècnica de Catalunya, 2020-02-14)
      Master thesis
      Open Access
      The lower thermosphere (between 100 and 250 km) is badly known due to the scarcity of operating satellites in this region. Nevertheless, it is very relevant for the study of Earth-Sun relations, satellite re-entry ...
    • 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
      Open Access
      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 ...
