that can be received by a special receiver on the
boat. Differential beacons are usually only
installed near ports and important waterways,
and each beacon has a limited range. The
accuracy of the corrected GPS position is
typically better than 2 to 5 m (6 to 16 ft).
To use differential beacon DGPS, the TRACKER
must be installed with an external DGPS antenna,
such as the NAVMAN DGPS 1 (see section 15-3).
Startup
