I believe that the best is yet to come, although a large majority does actually exist within everyday farm life.
As time goes by, farms will wonder how they ever managed without a Satellite GPS system.
The ability to map out your land, prevent overlapping of your application, and improve productivity whilst of course reducing costs, can all be obtained by the latest technology.
Never has it been so easy to purchase a GPS system for a minimal cost and more importantly know how to operate it. Most systems now can even be moved from machine to machine within a matter of minutes.
The accuracy can no longer be discounted. The crops themselves clearly show how much of an advantage GPS can be. The spreading of fertiliser on grass is now made so ridiculously easy that you cant imagine how you ever managed without it.
I can only presume that the future will bring GPS as standard kit in any manufacturers cab and that the technology will of course continue to improve. Certain manufactures are already working on systems that can initiate the headland turn for you.
Auto steer is already with us, and having already tried this myself, I just cannot correct the tractor in the way that the GPS can. In other words the electronics can drive the tractor more smoothly and accurately than I can.
GPS systems are not just an advantage to the large arable farmer either. Many smaller farms are finding a huge advantage, by simply using the system for spreading fertiliser or spraying.
The initial cost of a GPS system, should certainly be paid back within the first 1 to 2 years, thanks to its efficiency.
However don't tell your granddad that you need a box of tricks to find your way out of the field.
