USCG open public comment period on DGPS stations

NATIONWIDE —The U.S. Coast Guard, U.S. Army Corps of Engineers, and the Department of Transportation are seeking comment on a proposal to reduce coverage provided by the Nationwide Differential Global Positioning System (NDGPS).

The proposal calls to the shutdown and decommissioning of 62 DGPS sites, leaving 22 operational sites available to users in coastal areas.

According to the news release, NDGPS service augments GPS by providing increased accuracy and integrity using land-based reference stations to transmit correction messages over radiobeacon frequencies. A number of factors have contributed to declining use of NDGPS and, based on an assessment by the Department of Homeland Security, Department of Transportation and the Army Corps of Engineers, are proposing to shutdown and decommission 62 DGPS sites, which will leave 22 operational sites available to users in coastal areas.

Termination of the NDGPS broadcast at these sites is planned to occur Jan. 15, 2016.

Comments must be received by Nov.16, 2015.
