Anecdotally, the new NavX firmware improves upon that drift.

I don't know that triangulation is the right term for this. I think you might be after something similar to Simultaneous Localization And Mapping (SLAM). SLAM is becoming more common in consumer and hobbyist robotics but it's still early days yet. I can tell you that it is something to keep digging into but I'm not sure it is the best area to invest resources into for an FRC team. It is definitely cool stuff though.
