Design of a solar sail as the propulsion system for a nanosatellite
(Universitat Politècnica de Catalunya, 2013-06)
Projecte/Treball Final de Carrera
Accés obertThis project presents the design of a solar sail as a feasible solution to thrust nanosatellites. A solar sail is a high-energy space propulsion system that uses solar radiation pressure to push large ultra-thin mirror to ... -
Estudio sobre la viabilidad de un star tracker de bajo coste
(Universitat Politècnica de Catalunya, 2015-01-09)
Treball Final de Grau
Accés restringit per decisió de l'autorLos sistemas de orientación de antenas o telescopios son elementos indispensables para múltiples aplicaciones como observaciones astronómicas o telecomunicaciones. El coste de dichos sistemas depende sobre todo de la ... -
Optimization of interplanetari trajectories with gravity assist
(Universitat Politècnica de Catalunya, 2020-07-28)
Tesi
Accés obertInterplanetary travel is a difficult task due to the high fuel mass required to reach other planets. Minimizing the cost of the manoeuvres (and, in turn, the fuel mass) is the objective preliminary mission design. During ... -
Study of a lunar satellite navigation system
(Universitat Politècnica de Catalunya, 2012-09)
Projecte/Treball Final de Carrera
Accés obertThe objective of the present study is to hold a preliminary analysis and design of a lunar global satellite navigation system able to provide accurate positional information to operators on the surface or in low lunar ... -
Study of advanced materials for thermal insulation in the inner Solar System
(Universitat Politècnica de Catalunya, 2014-09)
Projecte/Treball Final de Carrera
Accés obertSpace harsh environmental condition often calls for an adequate thermal regulation and insulation. In this thesis, a thermal model for a greenhouse in Mars is presented. Its objectives are to achieve and maintain suitable ... -
Study of Earth-Moon trajectories with solar sail propulsion
(Universitat Politècnica de Catalunya, 2014-09)
Projecte/Treball Final de Carrera
Accés obertThe computation of Earth-to-Moon trajectories constitutes an important and interesting chapter of spacecraft trajectory design. The traditional techniques based on Hohmann maneuvers and patched conics allowed the fast ... -
Study of Earth-to-Jupiter transfers with gravity assist at Mars using the C3 matching technique
(Universitat Politècnica de Catalunya, 2016-06-22)
Treball Final de Grau
Accés restringit per decisió de l'autorSpace exploration arouses a great interest in the scientific community and, each time, it is intended to deal with more complex and ambitious missions. Nowadays, the computing power allows modelling accurate force fields ... -
Study of Earth-to-Mars transfers with low-thrust propulsion
(Universitat Politècnica de Catalunya, 2011-09)
Projecte/Treball Final de Carrera
Accés obertKnowledge and investigation about low-thrust propulsion systems have been increasing during the last years and some spacecrafts employing this technology have succeeded in their objectives, which contribute to the possible ... -
Study of end-of-life disposal options for highly-inclined geosynchronous satellites
(Universitat Politècnica de Catalunya, 2016-06)
Treball Final de Grau
Accés obertIn recent years, the growing volume of activities in the northern regions (Arctic, Canada, Northern Russia) has produced an increasing request for communications services. Several studies have concluded that there are ... -
Study of spacecraft orbits in the gravity field of the moon
(Universitat Politècnica de Catalunya, 2012-01)
Projecte/Treball Final de Carrera
Accés obertThe objective of the present study is to analyze the evolution of low lunar orbits under the gravitational potential of the Moon and additional perturbations of gravitational (Earth and Sun gravity) and non-gravitational ... -
Study of the Martian environment for application to the design of a greenhouse
(Universitat Politècnica de Catalunya, 2014-07)
Projecte/Treball Final de Carrera
Accés obertThe human exploration of Mars belongs to the current plans of NASA and ESA. Getting the astronauts to Mars and returning them safely to Earth imposes several engineering challenges. In particular, creating the conditions ... -
Study of the mechanical response of the LTP's test masses due to the action of control heaters in LISA Pathfinder
(Universitat Politècnica de Catalunya, 2011-01)
Projecte/Treball Final de Carrera
Accés obertThe main aim of the LISA Pathfinder (LPF) mission is to place two Test Masses into a very stable drag free environment and make very precise interferometric measurements of displacements between them. In order to achieve ... -
Study of the optimal approach and detection phases for missions to small asteroids
(Universitat Politècnica de Catalunya, 2015-01)
Projecte/Treball Final de Carrera
Accés obertNowadays, small asteroids are catching the space community’s attention and interest. Instead of planning expensive missions to planets, missions to small asteroids (<100m) are of interest both because of their lower costs ... -
Study of the performance of an inertial measurement unit on board a launcher
(Universitat Politècnica de Catalunya, 2014-03)
Projecte/Treball Final de Carrera
Accés obertCurrent predictions indicate that by 2020 the available launchers will not cover the market niche of small satellites. The Aldebaran launcher is intended to cover this market niche. Aldebaran will perform an aerial launch ...
