Overview

Nowhere has the fact that GNSS can guide things besides military weapons and transport manifested itself more profoundly than in agriculture.

While Google and automotive manufacturers struggle to figure out how to put autonomous vehicles on the highway, farmers have been using GNSS for well over a decade to guide equipment through their fields — along with a host of other ag-related, site-specific applications.

Indeed, GNSS — along with an array of other high-tech resources — is transforming agriculture at an accelerating rate.

To help us get our arms around the state of the arts and sciences in precision farming, we turned to Dr. John Fulton, associate professor in the Department of Food, Agricultural, and Biological Engineering at Ohio State University. Previously the assistant manager of a 2,000-acre, family owned fruit and vegetable farm in Ohio for 24 years, Fulton has conducted research and written extensively on the use of advanced technologies on U.S. farms of which he estimates around 70 percent are using some level of GPS/GNSS.
