I think due to the implants most of the imaging system is shunted into Brera's mind similar to the way cyborgs control technology and communicate through networks in Ghost in the shell SAC, also it must have it's root in the BCS system that was shelved after Guld(you, lol) maned up and did what was needed, it's only natural that a technology based colony fleet would dig up tech that was similar to it's needed goals.
