FYI. Looks like the CORS site in Pueblo will be affected.

Subject: CGSIC: FW: Federal Register Notice regarding NDGPS
To: “cgsic@cgls.uscg.mil” <cgsic@cgls.uscg.mil>
All CGSIC:
The Federal Register has issued a “Notice: Request for Public Comments”
from the Coast Guard (USCG), the Transportation Department (DOT), and the
Corps of Engineers (USACE) dated 08/18/2015. The Nationwide Differential
Global Positioning System (NDGPS) service augments GPS by providing
increased accuracy and integrity using land-based reference stations to
transmit correction messages over radiobeacon frequencies. The service was
implemented through agreements between multiple Federal agencies including
the USCG, DOT, and Army Corps of Engineers, as well as several states and
scientific organizations, all cooperating to provide the combined national
DGPS utility. However, a number of factors have contributed to declining
use of NDGPS and, based on an assessment by the Department of Homeland
Security, DOT, and USACE, DHS, DOT, and USACE are proposing to shutdown and
decommission 62 DGPS sites, which will leave 22 operational sites available
to users in coastal areas. This notice seeks public comments on the
shutdown and decommissioning of a total of 62 DGPS sites. Termination of
the NDGPS broadcast at these sites is planned to occur on January 15, 2016.
You may view the Notice at
https://www.federalregister.gov/articles/2015/08/18/2015-20401/nationwide-di
fferential-global-positioning-system-ndgps. See the Notice for details
regarding submission of comments. Comments and related material must reach
the Docket Management Facility on or before November 16, 2015.
