Using GPS for positioning

"We are using GPS for positioning. That works perfectly even though we are under a bridge and close to electric lines. We have never had any interference with the signals and could always work. It’s a mega support for positioning the piles in the water."

Patrick Fuchs

Site Manager, Birchmeier Bau AG
