| Summary: | The growth in cost and complexity of traditional scientific missions along with the reduction in space budgets have determined space community to focus on small satellites that not only provide valuable scientific returns, but also allow completely new applications in remote sensing, environmental monitoring and communications. Furthermore, small satellite flying in formation is a key technology for many future space science missions, by improving mission survivability and reducing mission costs, and offering multi-mission capabilities, achieved through reconfiguration of formations.The main goal of this thesis is two-fold: proposing innovative nanosatellite constellation models andnew routing approaches for nanosatellite network telecommunications. Therefore, this research work proposes and analyzes three models of nanosatellite constellations, named NanoDREAM, NanoiCE, NanoSPHERE, that provide telecommunication services to remote regions of the Earth. NanoDREAM mode! is designed for Bolivia's Salar de Uyuni Desert, a region which detains 70% of the global lithium reserve. NanoiCE model is intended for Polar Regions, in order to meet the voice and data transfer needs of the entire Antarctic and Arctic scientific community. NanoSPHERE is aimed to provide global coverage in the context of a robust telecommunications market. Additionally, a ground segment architecture based on wireless technology and deployed over the exploitation area of Salar de Uyuni Desert was proposed. Moreover, two new methodologies were proposed: the first one is a method for estimating the number of nano-satellites needed to cover a specific region was, and the second one is a Markov modeling based method for evaluating the performance of nanosatellite constellations. [.] La réduction des budgets du domaine spatial et les missions scientifiques traditionnelles ayant des coûts et une complexité croissants a amené la communauté scientifique à se concentrer sur les petits satellites qui fournissent non seulement des résultats scientifiques ... |
