Welcome CMDR! This little tool is designed to solve triangulation puzzles in Elite Dangerous, such as those found in Listening Posts.
There's only a couple of them to solve, but it's very hard to do it using only the tools available in game.
So, if you want a better option than just brute force, but don't want to just look up the answers, then hopefully this app can help!
