MEMORANDUM OF AGREEMENT

**FOR THE ESTABLISHMENT AND OPERATION OF THE**

**NATIONWIDE DIFFERENTIAL GLOBAL POSITIONING SYSTEM**

**(NDGPS)**

THIS AGREEMENT IS MADE AND ENTERED INTO BY AND AMONGST:

Headquarters U.S. AIR FORCE Air Combat Command AND THE U.S. ARMY CORPS
OF ENGINEERS OF THE U.S. DEPARTMENT OF DEFENSE;

THE NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION OF THE U.S.
DEPARTMENT OF COMMERCE; AND

THE FEDERAL RAILROAD ADMINISTRATION, THE FEDERAL HIGHWAY ADMINISTRATION,
THE U.S. COAST GUARD, AND THE OFFICE OF THE SECRETARY OF TRANSPORTATION
OF THE U.S. DEPARTMENT OF TRANSPORTATION

**I. [PURPOSE]{.underline}:**

This Memorandum of Agreement (MOA), and such supplements as may be
agreed to, provide the basis for cooperative efforts among the U.S. Air
Force (USAF), the U.S. Army Corps of Engineers (USACE), the National
Oceanic and Atmospheric Administration (NOAA), the Federal Railroad
Administration (FRA), the Federal Highway Administration (FHWA), the
U.S. Coast Guard (USCG), and the Office of the Secretary of
Transportation (OST) in the establishment of the U.S. Department of
Transportation's (USDOT) Nationwide Differential Global Positioning
System (NDGPS) radionavigation service.

This agreement provides for the maximum use of existing infrastructure
and resources within each agency to the mutual benefit of all agencies
and the general public. Specifically, this agreement establishes the
overall policies, relationships, and responsibilities guiding
interagency activities necessary to establish, operate, and manage the
NDGPS as authorized by Section 346 of Public Law 105-66 of October 27,
1997 (Attachment A) including the temporary and permanent transfer of
mutually selected USAF Ground Wave Emergency Network (GWEN) sites and
equipment to USDOT.

**II.** **[BACKGROUND]{.underline}:**

In Presidential Decision Directive NSTC-6, *U.S.* *Global Positioning
System Policy*, (March 28, 1996), the President designated the USDOT as
the Nation\'s, "lead agency for all Federal civil GPS matters." In
addition, the President directed the USDOT to \"develop and implement
U.S. Government augmentations to the basic GPS for transportation
applications.\" The USCG established the Maritime DGPS Service, a GPS
augmentation providing service for coastal coverage of the continental
U.S., the Great Lakes, Puerto Rico, portions of Alaska and Hawaii, and
portions of the Mississippi River Basin. This service meets the
requirements of U.S. harbor entrance and approach areas defined in the
current version of the *Federal Radionavigation Plan*. Differential GPS
(DGPS) corrections are broadcast on long-established international
marine radiobeacon frequencies (285-325 kHz). The USCG Maritime DGPS
Service is operated in cooperation with the USACE and the National
Geodetic Survey.

The *Technical Report to the Secretary of Transportation on a National
Approach to Augmented GPS Services* (December 1994) recommended
implementation of a Coast Guard-like system for use in land navigation
and positioning applications in those sections of the nation not
currently covered by the USCG Maritime DGPS Service. To accomplish this,
the USDOT formed the DGPS Policy and Implementation Team under an
Executive Steering Group. The NDGPS Policy and Implementation Team found
that the current most viable GPS augmentation option which could satisfy
most surface applications needs is the DGPS operated to the *USCG DGPS
Navigation Service Broadcast Standard*, Commandant Instruction M16577.1.

During its study, the NDGPS Policy and Implementation Team learned of
the USAF plans to decommission the Ground Wave Emergency Network (GWEN).
GWEN provides emergency communications using fifty-three transmitter
sites located across the continental U.S. The Single Channel Anti-Jam
Man Portable (SCAMP) is to replace GWEN. The GWEN sites operate on
frequencies near the USCG DGPS radiobeacon frequencies. During 1997, the
USAF loaned the GWEN site located near Appleton, Washington, to the FRA
and USCG to be converted to a USCG DGPS station as a proof of concept.
The Appleton station provided DGPS coverage to the navigable portions of
the Columbia and Snake Rivers and the Positive Train Separation test-bed
supported by the FRA. Based on the successful results of this prototype,
the NDGPS Policy and Implementation Team determined that conversion of
GWEN sites to civil DGPS use provided a cost-avoidance opportunity in
the establishment of the NDGPS. The team presented its results to the
Executive Steering Group on August 14, 1997. The consensus of the
Executive Steering Group was to expand the Coast Guard's DGPS into a
nationwide system.

On October 27, 1997, Section 346 of Public Law 105-66 (Attachment A)
authorized the USDOT to establish, operate, and manage the NDGPS
including taking receipt of necessary GWEN sites and equipment. A
coverage plan was developed to meet FRA requirements for use in its
train-control initiatives. To complete the required coverage under this
plan, many of the GWEN sites will be converted at their current
locations, from other GWEN sites the equipment will be moved to
locations better suited for optimum coverage to the nation, and some
non-GWEN stations will be established.

The NDGPS project plans to install 65 to 75 sites under the scope of
this agreement. The final NDGPS will have 125 to 135 sites, including
the current Coast Guard and Army Corps of Engineers sites and the sites
installed under this MOA. These sites will be compatible with, and
integrated into, the Maritime DGPS Service operated by the Coast Guard
and the Continuously Operating Reference Station (CORS) network of the
National Geodetic Survey. Plans based upon historical Congressional
appropriations for the NDGPS project a completion date in Calendar Year
2003. The expected system life cycle is fifteen years.

**III. [IMPLEMENTATION AND FUNDING:]{.underline}**

Implementation of this MOA will be performed by the appropriate elements
of the USAF, USACE, NOAA, and participating USDOT agencies. For the USAF
the responsible organization is the USAF Headquarters Air Combat
Command. For NOAA the responsible organization is the National Geodetic
Survey (NGS). For the USACE the responsible organizations are the
individual field offices in coordination with their chain of command.
For the FRA the responsible organization is the Office of the Associate
Administrator for Railroad Development. For the FHWA the responsible
organization is the Office of the Associate Administrator for Research
and Development. For the USCG the responsible organization is the
Director of Operations Policy.

The NDGPS Policy and Implementation Team will conduct overall
coordination of the NDGPS. The functions of the NDGPS Policy and
Implementation Team are: to coordinate interagency actions affecting the
NDGPS; to serve as a forum to raise, discuss, and resolve issues
concerning the NDGPS; to monitor compliance with interagency memoranda
of agreement regarding the NDGPS; and to advise agencies as appropriate.
The team will consist of members from each of the organizations that are
signatories to this agreement. Members will be designated in writing and
each will be responsible for coordinating his or her organization's
activities and reporting those activities to the team. The team chairman
will be the representative from the USDOT OST.

The FRA, in coordination with the NDGPS Policy and Implementation Team
and the USCG, will submit and defend funding requests for the full cost
of providing the NDGPS. These requests are to include implementation,
operation, maintenance, and eventual decommissioning, including but not
limited to real property disposal and environmental remediation, and the
execution of the specified activities below. Agencies with funding
requirements are required to submit their requirements and cost
estimates to the FRA in sufficient time to enter the Congressional
budget cycle. The FRA shall specify submission dates as necessary.

No fund transfers are required to or from the USAF under this MOA.
Agencies will ensure adequate funding is available via direct
appropriation, transfer, or reimbursable agreement prior to undertaking
work associated with their responsibilities under this MOA. Agencies
shall be responsible for compliance with all laws, regulations, and
federal policies for obligation and management of funds as applicable.

The authority to establish, operate, and manage the NDGPS that is
granted to the Secretary of Transportation in Section 346 of Public Law
105-66 is delegated to the USCG in a Federal Regulation issued to Part I
of Title 49 of the Code of Federal Regulations. The delegation to the
USCG does not include the function of determining the Federal
requirements for the NDGPS, which is delegated to the FRA in the same
regulation. The delegation to the USCG also does not include the
function of acting as lead USDOT agency for matters relating to the
National Environmental Policy Act (NEPA), which is delegated to the FHWA
in the same regulation.

The parties agree that the FHWA will be the lead agency, as defined in
40 CFR 1501.5, for NEPA compliance for establishment of the NDGPS. The
parties agree to use the FHWA implementing regulations (23 CFR 771) for
environmental impact analysis and procedural compliance with NEPA. The
FHWA will prepare NEPA documents for the entire NDGPS program as well as
for specific sites and will distribute copies of all NEPA documents to
the cooperating agencies participating in NDGPS deployment. The FHWA may
request that cooperating agencies provide information and analysis in
areas of the cooperating agencies special expertise. The FHWA will give
the technical and environmental reviewers of each of the cooperating
agencies the opportunity to review and comment on the programmatic and
site-specific NEPA documents for technical accuracy and adequacy at the
preliminary draft stage (i.e. prior to release of the draft document to
the public) and at the preliminary final document stage (i.e. prior to
release of the final document to the public).
