A photo of a snow plow with DGPS.

This snowplow uses Differentially Corrected GPS (DGPS), which adds an extra "correction" signal from a transmitter on the ground to improve accuracy.

Using DGPS, it is possible to find the vehicle's position within a few centimeters. In the near future, this technology may help prevent vehicles from running off the road in poor visibility conditions.
