| Summary: | In this Master Thesis, numerical models of ADCS components are performed. The models will be used in the design of the first 3U CubeSat of the CSU Montpellier, the ROBUSTA 3-A. The goal of the thesis is to develop numerical models of angular rate sensors and reaction wheels and to obtain relevant information of these components in the context of the R-3A mission. Firstly, the state-of-the-art of models are outlined, and the most suitable are chosen. Secondly, assumptions are made, and the models are implemented. Next, the models are parametrized for specific elements to be used on R-3A. Lastly, the models are validated and simulated. The results of simulations confirm a choice of the CoTS components for the R3A mission. Besides, the results provide information about system performance parameters such as RW acceleration time, maximum satellite speed, and attitude knowledge accuracy in eclipse.
