Current constellations have a high launch cost so the use of signals of opportunity is an alter-
native that has proven to be effective. It uses existing constellations such as GNSS to obtain
valuable data from reflectometry (GNSS-R) for Earth observation. Furthermore, development
of FPGA-based receivers reduce even more this cost in a much more versatile and agile way.
This project describes a VHDL library that implements the GNSS signal tracking circuit with
the aim of developing a real-time opportunity signal processor.

The signals of the global navigation satellite’s were designed for having a pre- established function
of geolocation. However, using these signals we can pull out some profit in other aspects that
were not originally the main focus of interest. This signals are named ”signals of opportunity”and
are used outside the main objective that were come up with. In this project they will be used
in oceanic altimetry applications. Applying different windowing techniques to the GPS signals
and also the digital television signals by satellite’s, the aim is to influence in the shape of
the ambiguity function in the direct wave reception as well as in the ocean surface reflection,
modifying the main lobe and the sidelobes of the function.

With the goal of innovating in the aerospace sector, this final project aims to introduce the usage of Python code in order to control microsatellites. These types of satellites use microcontrollers, with scarce resources, with the purpose of reducing its volume and cost. Its limitations mean that embedded software must be developed to fully exploit its potential, leaving behind other programming languages, as interpreted ones. The aim of this project is to break this rule and achieve that the Space Science Institute’s software for controlling microsatellites, allow its users to use Python for creating microsatellite’s control sequences.

This project is part of the initiative carried out by Institut de Ciencies Espacials de ` Catalunya, Universitat Politecnica de Catalunya and Institut de Ci ` encies de l’Espai [5]. This initiative aims to develop a Cubesat microsatelite from the ground without depending on third parties. A Cubesat is a microsatellite formed by one or more cubes of standard size (10 x 10 x 11.35 cm) that work with commercial components, that is, mass produced components available at any store, not made specifically for the space environment[1]. Their main advantage is the low cost not only of the manufacturing, due to the low cost of the components and the possibility of reusing them, thus amortizing the development, but also in the launching, since they are sent as an extra cargo of other bigger launches. Their main disadvantage is their short lifespan, because of the components used. This project was offered by the ICE and its purpose was to develop a driver for the radiofrequency transceiver of the CubeSat to make it able to communicate to and from earth. In this paper the process followed to develop this driver is shown.

El propósito de este trabajo es lograr un mejor entendimiento de los mecanismos de formación de las estrellas. Concretamente, analizaremos el fenómeno de la multiplicidad estelar desde su raíz; centrando nuestra atención en las primeras etapas de la formación protoestelar, y en su evolución desde protoestrellas de Clase 0 hasta Clase I.
Para ello, comenzaremos con una introducción teórica donde se expondrán las condiciones físicas necesarias para el proceso de formación de estrellas; desde el equilibrio de fuerzas en las nubes moleculares hasta las dinámicas de colapso en sus núcleos densos. A continuación produndizaremos en los diversos parámetros que afectan a la multiplicidad de los sistemas jóvenes, basándonos tanto en observaciones como en simulaciones realizadas durante las últimas dos décadas. Nuestro objetivo será encontrar una serie de correlaciones que nos permita describir el comportamiento general de este tipo de protoestrellas.
Concluiremos con un estudio detallado de la región occidental de la nube molecular de Perseo, contrastando los datos observacionales de numerosos artículos y discutiendo sus resultados.

The Institute of Space Studies of Catalonia and the Institute of Space Sciences are currently carrying out a project called C3SatP which consists in the design and prototyping of a nanosat of its own manufacture that allows to provide adapted solutionsto possible needs within the territory of Catalonia. The scope of this work is, mainly, software development, following an engineering process, of one of the components of this nanosatellite, called On Board Data Handler. In addition, it has also been requested to develop a state machine for the base software of the entire nanosatellite. The methodology consisted in meeting with the tutor every two weeks, where the requisites were established as they appeared, in addition to making a specification requirements document. Later, the design of the functionalities using class diagrams, sequence diagrams and user cases. Finally, the implementation of the software and the test cases that guaranteed compliance with the requirements, in C and C ++ language respectively, and using version control. To carry out the project, learning different tools and technologies have been needed, such as IDEs, use of external libre. As a result of the entire engineering process, most objectives which they had been considered at the beginning, have been achieved

In the Interstellar Medium, star formation occurs in regions where density is high and the temperature is low, that leads to the Molecular Clouds, which are the places where stars are born. In order to observe these star formation sites, we use the emission of the ammonia (1,1) and (2,2) transitions, obtained by the Green Bank Telescope. This project pretends to analyze the Pipe’s Nebula region Barnard 59 using temperature, velocity and emission line width maps, as well as look into the Young Stellar Objects that are being formed within it, its distribution, itsmolecular outflows and the overall structure and kinematics of the core alongside the spiral arms around it. In order to do that, we have used the HfS, a tool that adjusts pixel by pixel the hyperfine structure of the NH3 emission lines. First of all, there is going to be an introduction to the basics, which are the InterstellarMedium, star formation, the Pipe Nebula and Barnard 59. Then, we will look into the molecular transitions and the technical aspects of the performed observations. Later, we will explain how the HfS tool works and the results of the analysis for every mapped area. To sum up, the conclusions of the project will be given.

Chondrites are undifferentiated meteorites that are representative of the materials
forming the protoplanetary disk, about 4.5 Ga ago, because their parent bodies did not
chemically differentiate, due to their size smaller than a few hundred kilometers. These
meteorites are interesting samples because they exhibit bulk compositions close to the
original ones when they accreted. Most chondrites have only suffered mild thermal
alteration, but some exhibit clear evidence of wet accretion and ulterior aqueous
alteration, which exemplify its post-accretionary history and evolution. The study of these
parent body processes, from the evidence preserved in chondrites, is very interesting
because it can lead to understand the pathways of Solar System formation and its
evolution. Carbonaceous chondrites, a specific class of chondrites, are especially
interesting because they contain large amounts of organic matter that can provide some
clues on how life could have evolved here on Earth.  
The subject of study of this work is Graves Nunataks 95229 (GRA 95229), a CR2
chondrite from the NASA Antarctic collection. It is a very pristine sample with interesting
signs of alteration processes and it exhibits a fascinating proportion of organic complex
compounds, about one order of magnitude higher than the famous Murchinson CM2
chondrite.  The aim of this work is to undergo a mineralogical and petrological analysis of GRA
95229 using different spectroscopic techniques; i. e., SEM/EDX and Raman
spectroscopy, to obtain clues about the alteration effects caused by parent body
alteration and the collisions suffered by it. Additionally, quantum mechanical methods
have been used to simulate the Raman spectra of different minerals, commonly present
in meteorites, and they have been compared to the experimental spectra to identify more
precisely the mineral composition and the signs of alteration and thermal annealing
experienced by this meteorite as consequence of shock.
