The ability to conceal a starship's identifying signals was provided by the signature modulator, a stealth innovation employed in the Age of the Empire. The crew of the Ghost utilized a modulator to hide from the Imperial Navy by making their ship appear to be the Tontine while undertaking a job run alongside Lando Calrissian, a smuggler. Furthermore, Senator Mon Mothma's Taylander shuttle, known as the Chandrila Mistress, also incorporated a signature modulator.
