The rings on the puzzle match planets on corresponding orbits (you can notice that cross-shaped star near the planet on the outer orbit matches the cross-shaped star symbol on the puzzle).

Look in your Memory.

If you examined almost all the posters, the ones about specific planets also show you their symbols

I stopped playing the game right before this puzzle and i had completely forgotten about the star map by the time i played again...
Hilariously enough, i partially solved it by thinking that one of the symbols present on every replika presentation document was a hint ( the circle containing a tiny circle at its bottom left ). I had to brute force the other 2 symbols, now i kinda wish i'd remembered the star map cause this is a pretty cool puzzle...
