RESPONSIBILITIES OF THE CANDIDATE : The main objective of this Master’s research project is to develop a satellite constellation perturbation model generator for the hybrid GNSS signal simulator. The main part of the work deals with the simulation and analysis of the satellite constellation perturbations. Several models will be taken into account, implemented and tested, such as satellite failure models and satellite reference oscillator models. The developed algorithms will be implemented in Matlab/Simulink for performance evaluation. The algorithms will also be implemented in the real-time platform and the results obtained will be compared with the simulation results. An exhaustive analysis will be performed in simulation and in real time in order to assess the influence of all these perturbation models on the performances of the GNSS signal simulator, and this study will be done for all the GPS and Galileo considered frequencies. This 12 month Master’s Degree research project will start with a meticulous analysis of the various satellite constellation perturbation models available in the literature. The Master’s student will be supervised and will work with the postdoctoral researcher and will regularly meet with the professor in charge of the project. He will collaborate with other Master’s student who will study more in details the real-time aspects and validation of the algorithms.
