In this communication, we investigate the late-time dynamics of a tachyon cosmological model in the presence of a supergravity tracking potential. By assuming a particular relation between the Hubble parameter, the tachyon scalar field and its time derivative, an exact solution of the model is constructed. It was observed that the universe is oscillating with time and dominated by an oscillating tachyon field. Special properties and features were derived accordingly.
