Using quantum sensors, the company achieved ten times the accuracy of conventional satellite-based navigation systems, while maintaining the one nautical mile positioning accuracy.
Don’t we use GPS accurate to within centimeters for construction?

I’ve played with GPS from several different directions. There are a lot of GPS receivers on the hobby electronics market that will offer that level of precision, but not accurately. The aviation wide area augmentation system significantly increases accuracy to the point it can be used for precision instrument approaches.
