Neutral Hydrogen (HI) Intensity Mapping (IM) promises to open a new window for cosmology, probing Large Scales Structures (LSS) in the Universe over a wide range of redshifts. Unfortunately, HI IM is contaminated by several effects, one of these is the emission from artificial satellites. We aim to simulate the Radio Frequency Interference (RFI) emitted from the Global Navigation Satellite System (GNSS) for the MeerKAT Single Dish HI IM observations, focusing on the 1000-1500 MHz frequency range. We fit our satellite model to data taken using the MeerKAT telescope and study the impact of the residual contamination in the supposedly RFI free regions.
