- Objectives
This Bachelor's Thesis aims to address the design and implementation of the GNSS receiver based on the switching matrix technique for the 3Cat8 satellite mission, developed by NanoSat Lab. A design will be proposed that integrates the existing antennas with the satellite's receivers, taking into account the scientific needs of the mission. Including a selection of components that meet the necessary standards for the space environment. Additionally, the PCB design will be crafted to efficiently integrate the switching matrix with the rest of the system, and its functionality and reliability will be tested. Methodology: - Methodology 1. Identification of the scientific requirements of the mission in terms of GNSS-R and GNSS-RO to determine the functional needs of the switching matrix. 2. Conceptual design of the switching matrix and selection of components to generate the integral block of the GNSS receiver. 3. Elaboration and implementation of the PCB. 4. Testing and validation. - Expected results: The expected result is to achieve a fully functional GNSS receiver based on the switching matrix technique and successfully integrated into the 3Cat8 satellite system, with a proper PCB design that ensures reliable data transmission. |

Overview (resum en anglès): | |
This final degree project focuses on the development of a GNSS (Global Navigation Satellite System) receiver block, based on a radiofrequency switching matrix. The main objective is to take the first step towards the operability of the satellite navigation system and the receiver for reflectometry and radio occultation experiments.
This project is carried out in collaboration with UPC NanoSat Lab, a department of the Universitat Politècnica de Catalunya specialized in launching nanosatellites for earth observation. Specifically, within the framework of the 3CAT-8 mission, the phenomenon of ionospheric scintillation is being investigated, that is, how radiofrequency waves are affected when crossing the ionosphere. Additionally, it aims to monitor radio frequency interference (RFI) in the L and K frequency bands as a secondary objective. This project involves a deep theoretical study on GNSS concepts and their implications in reflectometry and radio occultation fields. Next, the different subsystems of the satellite are thoroughly explored for the generation of a comprehensive design that will integrate existing antennas with receivers, considering the scientific requirements of the mission and selecting components according to space standards. Furthermore, the necessary printed circuit boards are developed for efficient integration of the switching matrix with the rest of the satellite subsystems, always respecting the basic characteristics of GNSS signals and their fundamental properties. This project represents the first step towards the culmination of the satellite system responsible for conducting the scientific tests of the 3CAT-8 mission. |
