One of the latest cutting edge applications of precision GPS is
in the field of automated machine operation. In agriculture, forestry
and construction, these applications have become indespensible for
working vast tracts of land efficiently and effectively.
One example where precise and accurate real time positioning is
used for automated machine operation is on farms, where harvesting
machines make short, light work of a harvest-ready field. Such
cropping machines are driven on planned routes, and steered
using real time GPS positioning.
A more recent innovation uses a similar technology in machines for
the construction industry. For example a bulldozer can be fitted with
sensors at their hinges, so that its movement can be controlled remotely,
and its actions programmed for automated ground clearing.
The future trend of this industry appears to favour the
use of automated steering and guidance, as evidenced by the
developing market for such GPS technology. This technology is
an exciting push into the frontiers of precise positioning application.
