How accurate is FarmNav?
FarmNav uses the built-in satellite positioning of your phone, typically achieving 3 to 5 meters of accuracy in good conditions. It is not RTK and does not offer sub-inch precision, with accuracy potentially dropping under tree canopy or near buildings.

Does FarmNav steer the tractor?
