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 United States Coast Guard (USCG), Department of Transportation (DOT), and United States Army Corps of Engineers (USACE), 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 (DHS), 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.

Background and Purpose

    The Coast Guard (USCG) began development of the Maritime 
Differential Global Positioning System (MDGPS) in the late 1980s. The 
GPS Standard Positioning Service (SPS) lacked sufficient accuracy and 
timely integrity monitoring, and soon later, was unable to meet 
requirements for coastal and Harbor Entrance and Approach (HEA) phases 
of navigation found in the International Association of Marine Aids to 
Navigation and Lighthouse Authorities (IALA) R-121 and International 
Maritime Organization (IMO) A.953(23) recommendations, and to support 
the buoy positioning mission. The differential technique used by DGPS 
employs the installation of navigation equipment at a precisely known 
location. The equipment receives the GPS signal and compares the 
position solution from the received signal to its known location. The 
result of this comparison is then generated in the form of a correction 
message and sent to local users via radiobeacon broadcast to improve 
the accuracy and integrity of GPS-derived positions. In March of 1999, 
the MDGPS service was certified to meet the performance standards 
required for HEA navigation with its 49 geographically dispersed sites 
providing coverage to a number of ports and waterways in the contiguous 
United States, Alaska, Hawaii, and Puerto Rico. MDGPS provided improved 
horizontal positioning accuracy of better than 10 meters, integrity 
(signal accuracy and continuity of delivery checking) alarms for GPS, 
and MDGPS out-of-tolerance conditions within 10 seconds of detection.
    In 1997, the Department of Transportation and Related Agencies 
Appropriations Act of 1998 (Pub. L. 105-66, section 346 (111 Stat. 
1449)) authorized the implementation of the inland component of the 
system. As a result, 29 additional inland sites were added to the 
network. These sites, along with seven sites provided by the U.S. Army 
Corps of Engineers, became known as Nationwide DGPS (NDGPS). The USCG 
was designated as lead for implementation, operation, and maintenance 
of the service. DOT is the NDGPS sponsor and chairs the multi-agency 
NDGPS Policy and Implementation Team (PIT) which directs the overall 
management of the NDGPS system. In cooperation with DOT, DHS, and 
USACE, many states and scientific organizations are also beneficiaries 
of the DGPS system, such as the National Weather Service's Forecast 
System Laboratory for short-term precipitation forecasts, and the 
University NAVSTAR Consortium for plate tectonic monitoring.
    However, a number of factors have contributed to the declining use 
of NDGPS. Contributing factors include: (1) USCG changes in policy to 
allow aids to navigation (ATON) to be positioned with a GPS receiver 
using Receiver Autonomous Integrity Monitoring (RAIM), which assesses 
the integrity of a GPS signal within the receiver; (2) increased use of 
Wide Area Augmentation System (WAAS) in commercial maritime 
applications, which uses ground-based reference stations and satellite 
communications to improve accuracy; (3) limited availability of 
consumer-grade NDGPS receivers; (4) no NDGPS mandatory carriage 
requirement on any vessel within U.S. territorial waters; (5) the May 
1, 2000 Presidential Directive discontinuing GPS Selective Availability 
http://clinton4.nara.gov/WH/EOP/OSTP/html/0053_2.html; (6) continuing 
GPS modernization; and (7) the DOT Federal Railroad Administration's 
determination \1\ that NDGPS is not a requirement for the successful 
implementation of Positive Train Control (PTC), which provides the 
railway system the capability to positively enforce movement 
authorities along railroad systems.
---------------------------------------------------------------------------

    \1\ Letter from Federal Railroad Administration to USCG dated 
January 29, 2013 with subject ``Elimination of the Requirement for 
the NDGPS to support PTC mandated by the RSIA of 2008.''
---------------------------------------------------------------------------

    In April 2013, DHS and DOT published a notice in the Federal 
Register \2\ announcing that DHS and DOT were in the process of 
analyzing the current and future user needs and requirements for NDGPS, 
and requesting public comment on:
---------------------------------------------------------------------------

    \2\ 78 FR 22554 (Apr. 16, 2013). The Notice was published under 
docket numbers, USCG-2013-0054 and RITA-2013-0001.
---------------------------------------------------------------------------

    (1) The commenter's usage of NDGPS for positioning, navigation, and 
timing;
    (2) The impact on NDGPS users if NDGPS were discontinued;
    (3) If NDGPS were discontinued, the possible alternatives for 
meeting users' positioning, navigation, and timing requirements; and
    (4) Potential alternative uses for the existing NDGPS 
infrastructure.
    The response to the 2013 notice was limited, but the responses 
received were well informed on the NDGPS system, its

[[Page 50020]]

use, and current and potential applications. While a limited number of 
responders found the broadcast of corrections to be beneficial, no 
respondents reported the discontinuance of DGPS broadcast to be 
detrimental or harmful. Ship pilots in particular noted that DGPS can 
be critical in confined waterways for precise shiphandling maneuvers.
    Several commenters noted that NDGPS is part of the Continuously 
Operating Reference Stations (CORS) \3\ network, which is used with GPS 
data to improve the precision of positioning, has value while others 
stated they had alternative networks available. The USCG cooperates 
with National Oceanic and Atmospheric Administration's (NOAA) National 
Geodetic Survey (NGS) to supplement their network of CORS reference 
stations with NDGPS sites. Today, DGPS sites account for approximately 
5% of the CORS network, which is comprised of more than 1,900 geodetic-
grade GPS receivers. CORS is widely used by Federal, state, and non-
government entities throughout the United States to provide data for 3-
dimensional positioning for use in land surveys, Geographic Information 
Systems (GIS), Land Information Systems (LIS), and environmental 
management. Additionally, raw GPS data is provided to NOAA's National 
Weather Service from all DGPS sites for weather analysis and 
prediction.
---------------------------------------------------------------------------

    \3\ CORS support surveying, mapping, and related disciplines 
that have accuracy requirements which require the use of a relative 
positioning technique. CORS automatically collect and record the GPS 
data at known locations in support of these activities.
---------------------------------------------------------------------------

    A few respondents noted the broadcast signals provide non-line-of-
sight benefits. Respondents suggested alternatives to NDGPS as 
currently implemented, such as using existing NDGPS stations to 
rebroadcast WAAS corrections, adding other data to the broadcast, 
integrating the broadcast with positioning technologies, or simply 
streaming data from the reference stations.
    After considering the comments and based on an assessment by DHS, 
DOT, and USACE, we propose to shutdown and decommission 62 sites, which 
is planned to occur on January 15, 2016, which will leave 22 
operational sites available to users in those waterway where pilots 
generally operate, i.e., where marine traffic is most frequent and the 
need for precise marine navigation is greatest. However, it is possible 
for the reference stations to be transitioned to other Federal, state, 
and/or local agencies. Questions about potential transition of specific 
reference stations should be directed to the individual(s) referenced 
in the FOR FURTHER INFORMATION CONTACT section above.
