Introduction
Cautions
All differential beacon receivers decode correction data
determined at the beacon transmitter site via a GPS
receiver(s). The GPS system is operated by the govern-
ment of the United States which is solely responsible for
their accuracy and maintenance. The DGPS beacon
transmitters are operated by the U.S. Coast Guard (or
similar government agency in other countries) which is
responsible for their accuracy and maintenance. The
Global Positioning System and the Differential Global
Positioning System are under development and are subject
to changes which could affect accuracy and performance
of all DGPS equipment. Although a DGPS system is a
precision electronic NAVigation AID (NAVAID), any
NAVAID can be misused or misinterpreted, and therefore
become unsafe. Use the DGPS system at your own risk. To
reduce this risk, carefully review and understand all
aspects of this Owner’s Manual and carefully compare
indications from your GPS receiver to all available
navigation sources including the information from other
NAVAIDs, visual sightings, charts, etc. For safety, always
resolve any discrepancies before continuing navigation.
