How John Deere developed one of the best GPS locators in the world

Dual-frequency GPS makes for greater accuracy, thanks to a better ability to correct errors introduced by atmospheric interference.

It’s difficult to argue that John Deere’s ISG hasn’t made farming a lot more sophisticated than the popular imagination of agriculture. The obsession with precision is everywhere – water sprayers correct for rotation speed when making turns, to ensure that soil at the inside of the curve receives precisely the same amount of water as soil at the outside; nutrient and moisture information can be precisely tracked, down to the square inch, and correlated against past yield data.

And the biggest difference, according to the Deere engineers, is that this simply makes life easier for the farmer of today, compared to his or her predecessors.

“Your options are a lot more open when you’re accurate,” said Pritchett.
