Differential GPS

This feature is described here not because it is really relevant to yacht navigation at the time of writing (2005), but in order to ensure that the full picture is understood lest the current situation change.

Differential GPS (DGPS) upgrades the accuracy of the standard GPS position by comparing the GPS-fixed position of a static, ground-based receiver at any moment with its known geographic position. The ground station transmits signals to all GPS receivers in its vicinity, advising them of any error it has noted. The differential user's receiver then incorporates this data into the fix that appears on its screen. Accuracy of a metre or so can then be expected.
