I SPECIAL NOTICES

ALASKA - KENAI - DGPS

Kenai is the newest site in the Coast Guard\'s west coast Differential
GPS (Global Positioning System) network. The new authorized transmission
mode is 310 khz, 170nm range, 100 bps.

Special note: Differential GPS beacons have been modulated with a
correction signal, which is used to improve the accuracy of GPS.
Aviation users are cautioned that DGPS corrections degrade performance
of some automatic direction finders used in aviation applications.
During DGPS system implementation, Coast Guard DGPS broadcasts are
unmonitored. Users may experience service interruptions without advance
notice. Coast Guard DGPS broadcasts should NOT be used under any
circumstance where a sudden system failure or inaccuracy could
constitute a safety hazard. When a DGPS broadcast site becomes fully
operational, an announcement in the Local Notice to Mariners will be
made stating that the DGPS broadcast is available for navigation use.
Status of Coast Guard DGPS broadcasts may be obtained from the Coast
Guard Navigation System Center (NAVCEN) at (703) 313-5900. Furthermore,
DGPS corrections are dependant upon the reliablity of GPS. Current GPS
status recorded voice announcements may be obtained from NAVCEN at (703)
313-5905.

largest scale chart on which the correction appears. The word (Temp)
below the chart

number indicates that the chart correction action is temporary in
nature.

The letter (M) immediately following the chart number indicates that the
correction should be applied to the metric side of the chart only, and
