Supposedly, these fragments transmit the signals all across the system and may be found by investigating the wavelength. It is described by Ordis that the frequency--while constant, is far too weak to be caught by the Liset's antenna and that it would require a sophisticated antenna to fully catch the wave such as the satellite found in the Archwing Interception mission. Proof Fragments can be sold from your inventory for ‍ 750 each.
