An adaptive remeshing procedure for proximity maneuvering spacecraft formations
(2012)
Article
Accés obertWe consider a methodology to optimally obtain reconfigurations of spacecraft formations. It is based on the discretization of the time interval in subintervals (called the mesh) and the obtainment of local solutions on ... -
A stroboscopic control for the confinement of swarms in a spherical domain around the Earth
(2017)
Text en actes de congrés
Accés restringit per política de l'editorialSwarms of spacecraft are an idea that has been growing in interest in the last few years. This work focuses on the strategies and costs for the maintenance of a swarm of a large number of spacecraft in a close neighborhood ... -
Maneuvering spacecraft formations using a dynamically maneuvering spacecraft formations using a dynamically adapted finite element methodology
(2009)
Article
Accés restringit per política de l'editorialThe formation reconfiguration or the deployment of multiple spacecraft is a key issue that demands a robust methodology safely avoiding collision hazards. In this paper we present a systematic procedure to perform proximity ... -

Methodology and estimation costs for proximity maneuvering spacecraft formations in the vicinity of libration points
(2012)
Text en actes de congrés
Accés obertThe aim of this paper is to study and provide estimations of the cost of reconfiguration maneuvers in the neighbor- hood of L1 and L2 libration points of the Sun-Earth system. The problem is considered as a function of ... -
Proximity maneuvering of libration point orbit formations using adapted finite element methods
(Universitat Politècnica de Catalunya, 2010-02-04)
Tesi
Accés obertThis 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 ... -
Reconfiguration of spacecraft formations in the vicinity of libration points
(2009)
Text en actes de congrés
Accés obertFormation °ying is an important concept demanding reliable and accurate techniques for the recon¯gura- tion or the deployment of the spacecraft. This paper is a contribution to these set of techniques considering a ¯nite ... -
Spacecraft formations reconfiguration using finite element methodology with adaptive remeshing
(2010)
Text en actes de congrés
Accés obertWe 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 ... -
Tails and bridges in the parabolic restricted three-body problem
(2017-01-01)
Article
Accés obertAfter a close encounter of two galaxies, bridges and tails can be seen between or around them. A bridge would be a spiral arm between a galaxy and its companion, whereas a tail would correspond to a long and curving set ...
