The goal of the Baryon Acoustic Oscillations from Integrated Neutral Gas Observations - BINGO radio telescope is to detect Baryon Acoustic Oscillations (BAO) at radio frequencies through 21-cm Intensity Mapping (IM). The telescope will span the redshift range 0.127 $< z <$ 0.449 with an instantaneous field-of-view of $14.75^\circ \times 6.0^\circ$. In this work, we investigate different constructive and operational scenarios of the instrument by generating sky maps as they should be produced by the instrument. In doing this we use a set of end-to-end IM mission simulations. The maps will additionally also be used to evaluate the efficiency of a component separation method (GNILC). We have simulated the kind of data that would be produced in a single-dish IM experiment like BINGO. According to the results obtained we have optimized the focal plane design of the telescope. In addition, the application of the GNILC method on simulated data shows that it is feasible to extract the cosmological signal across a wide range of multipoles and redshifts. The results are comparable with the standard PCA method.
