I SPECIAL NOTICES

ALASKA - DGPS STATUS

The following Alaska DGPS sites will be off air on the dates shown:

Annette Island 111600Z to 150200Z Jun 96

ALASKA - DGPS

The Coast Guard DGPS service has been declared operational for
navigation. During this Initial Operational Capability (IOC) Phase,
users continue to be cautioned to use all available navigational tools
to ensure proper evaluation of position solutions. Problems identified
in the pre-operational phase are being resolved. Full Operational
Capability (FOC) of the DGPS service is anticipated when all operational
and support performance requirements are met. The seven Differential GPS
beacons listed below have been established to serve Alaskan waters.
These 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. For users on the
Pacific Coast encountering problems with DGPS or needing more
information, please call the Coast Guard Navigation Center, Western
Operations Branch at (707) 765-7612/7613.
