Abstract: One of the significant applications of pedestal is carrying and rotating antenna to precisely track satellites in space so that it can be possible to receive signals sent from the satellites. Three-axis pedestal is one of the best pedestals ever constructed and can be utilised in diverse fields due to not having any keyhole. However, it has not been proposed an accurate model for it until now. In this article, an accurate model of the three-axis pedestal system has been extracted. For extracting motion equations of the pedestal in which the Euler-Lagrange method has been used, both rotational movement and transitional movement have been considered to obtain a precise and comprehensive model of the system. Because of the inaccessibility of the actual model and also saving time and cost, the proposed model has been compared with the model simulated in SolidWorks and MATLAB software to carry out validation.
Keywords: mathematical model; mobile antenna; XYZ pedestal; modelling; validation; simulation.
