I'm working with a startup in Bethlehem, PA to create a crane-operator assistance device using extremely accurate GPS and computer vision to guide operators when lifting structural beams. If anyone is interested please feel free to reach out!

Assuming GP is talking RTK GNSS[0] it can be down to cm accurate with good techniques.

GNSS can technically get down to mm accuracy but that typically requires static sites with lots of data.
