Pro-Level GPS Machine Control Tips Every Contractor Should Know

Every contractor hits the same GPS machine control growing pains. We pulled tips from Caterpillar, John Deere, Komatsu, and Case -- four things their experts say consistently separate crews that make GPS work from those that don't.

Get Your 3D Grading Under Control: 4 Site Control Principles Every GPS Contractor Needs to Know

Poor site control is the number one problem we see from contractors running GPS machine control. Not bad models or broken equipment. Site control, the first step on every single project. We've seen it cost contractors two weeks of production, turn a correct machine control model on a balanced site into a mysterious site export, and force concrete footings to be redone because the control was rotated 2.8 degrees. Every one of those situations was avoidable.

A screenshot from a drone flight planning interface titled “DJI Mavic 3E Flight Planning for Topographic Survey Mapping” shows a mapped area with a green grid overlay and waypoint markers on the left. On the right, advanced settings display sliders for side overlap ratio (80%), frontal overlap ratio (80%), and margin distance. A note emphasizes that 80% overlap provides good photogrammetry results and should not be set below 70% for 3D mapping. A YouTube play button is centered over the image.
