Nowadays the number of satellites in orbit performing space
missions is increasing due to the useful applications and advantages that they can bring us. A space mission has a very high difficulty as it is composed of lots of subsystems and all of them have to work properly and in the most efficient way during launch and in the space environment. Furthermore, putting a satellite into orbit and the technology used to build it are very expensive. Therefore, in order to ensure safety and reduce the risk of the mission, tests and simulations must be performed and analysed to improve and adjust as much as possible the satellite system. The idea of this thesis is to perform and improve a software simulating an Earth Observation Mission with Small Satellite, that takes into account the different main subsystems of the satellite and studies its behaviour in the space environment conditions in order to obtain a simulation as close as possible to the real mission. The simulation software developed will be a very useful tool for companies to test the parameters of their own products and see the viability of the mission before performing any experiment or test and in this way, safe large quantities of money and time. The principal subsystems of the satellite that could be developed are the power system, thermal system, data budget, communication system and payload. Also, many different important concepts about a space mission and space environment can be investigated: duty cycle, revisit time, access time, eclipses of the satellite depending on its orbit, types of payloads and orbital propagators. |

Overview (resum en anglès): | |
The aim of this final degree project is to study and improve an existing satellite mission
simulator software developed using Matlab for Earth observation purposes. Firstly, the characteristics and structure of the existing software is analyzed so that everything is properly understood in order to define appropriate improvements. These improvements are applied to the orbital propagator, the different subsystems of the satellite (power, thermal, data ...), its modes and other important concepts about a satellite mission, so that the simulator is as much approximated as possible to the scenario of a real mission. Once the software improvements are implemented and validated a final satellite mission analysis example is elaborated. This mission consists in observing a geographical zone of the Earth with a real objective and constraints... Finally, the result of the project is a GUIDE application from the Matlab software so that satellite mission analysis simulations can be programmed and studied from it. By analyzing the mission objectives and constraints, the user can try different satellite designs, orbits, modes, ground stations... and realize a comparison between them to obtain the best possible result to achieve their objectives. The methodology used to develop the project is, firstly to develop a study of space mission typical parameters and concepts related to satellites from books and research papers so that a big theoretical background is achieved. With this knowledge acquisition, the existing software can be understand and improved by implementing them to the Matlab Software in the best possible way. The validation of this project is done by comparing the results of every new implementation, by itself and on the whole, with the first version of the simulator and with the theoretical background studied to check its reliability. |
