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 ... -
Four-body co-circular central configurations
(2012-02)
Article
Accés obertWe classify the set of central configurations lying on a common circle in the Newtonian four-body problem. Using mutual distances as coordinates, we show that the set of four-body co-circular central configurations with ... -
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 ... -
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, ... -
Horseshoe motion in the Restricted three-body problem
(2005-09)
Article

Impulsive transfers between lissajous libration point orbits
(2003)
Article
Accés obertA complete methodology for the transfer between two Lissajous orbits around the same collinear equilibrium point is developed making use of the geometry of the phase space around these points. The result of the study ... -
Low-thrust station-keeping control for lunar near rectilinear halo orbits
(Springer Nature, 2023-04-01)
Article
Accés obertThis paper studies a low-thrust station-keeping of near rectilinear halo orbits in the Earth–Moon quasi-bicircular dynamical model, and it is illustrated using resonant near rectilinear halo orbits as nominal orbits. The ... -

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 ... -
Natural configurations for formation flying around triangular libration points for the elliptic and the bicircular problem in the earth-moon system
(2014)
Text en actes de congrés
Accés obertThe concept of Satellite Formation Flying (SFF) means to have two or more satellites in orbit such that their relative positions remain constant or obeying a certain dynamical configuration along the trajectory. This ... -
Nonlinear dynamics in an extended neighbourhood of the translunar equilibrium point
(1995)
Article

Numerical exploration of the limit ring problem
(2013-04)
Article
Accés obertThe aim of this work is to provide an insight of an idealized model of a planetary ring. The model is a limit case of the planar circular restricted 1 + n body problem, where an infinitesimal particle moves under the ... -
On central configurations of the kn-body problem
(2019-08-15)
Article
Accés obertWe consider planar central configurations of the Newtonian kn-body problem consisting in k groups of regular n-gons of equal masses, called (k, n)-crown. We derive the equations of central configurations for a general (k, ... -
On co-orbital quasi-periodic motion in the three-body problem
(2019-01-01)
Article
Accés obertWithin the framework of the planar three-body problem we establish the existence of quasi-periodic motions and KAM $4$-tori related to the co-orbital motion of two small moons about a large planet where the moons move in ... -
On the central configurations of the planar 1 + 3 body problem
(2011)
Article
Accés obertWe consider the Newtonian 4 body problem in the plane with a dominat mass M. We study the planar central configurations of this problem when the remaining masses are infinitesimal. We obtain two diferent classes of central ... -
On the mechanisms of natural transport in the solar system
(2010)
Text en actes de congrés
Accés obertSome minor bodies in the solar system (i.e., comets, asteroids and planetary ejecta) are capable of performing transfers from their original location to very distant places, provided they possess sufficiently large ...
