Coordinates (Kholat)

I got my hands on the game and while I’m running, I notice the luminous coordinates, or rather I saw them for the first time in the place where the tower (the bunker where the door “runs away” at the beginning) went along them, led to another one on the bridge, went along those led to third. I'm not sure that I was going right, MB a coincidence, because I'm not a very good navigator. Is there any info about this: video, article? Is this a stupid place where I am now or a mosaic?
