To increase the accuracy down to under 10 meters, 95% of the time, two methods are currently available to civilian users: 1) DGPS, and 2) Post-processing.ĭGPS does its corrections in real time, but to receive the free US Coast Guard correction signals requires a differential beacon receiver ($300+ USD), an antenna (4’ whip or expensive H-field), and a power supply for the beacon receiver.

A laptop or Palmtop computer is also required to log the points in the field.įor a long time now, many posters on the -nav newsgroup have expressed their frustration with Selective Availability (S/A), the intentional scrambling of the civilian signals that makes it accurate only to 100 meters, 95% of the time. Much more accurate results than possible with an uncorrected standard GPS receiver.
