  The large-scale distribution of neutral hydrogen (HI) in the Universe is
luminous through its 21 cm emission. The goal of the Baryon Acoustic
Oscillations from Integrated Neutral Gas Observations -- BINGO -- radio
telescope is to detect baryon acoustic oscillations (BAOs) 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 would be
produced by the instrument. In doing this we use a set of end-to-end IM mission
simulations. The maps will additionally 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 such as 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
principal component analysis method.
