## Outline

- GPS Management Structure
- Civil GPS Service Interface Committee
- Relationship with the GPS Operations Center (GOC)
- Navigation Information Service

**Notes:**

I will briefly describe the Civil GPS Service Interface Committee role in the management structure and why we are collectively here. 

## GPS Management Structure

**GPS International**
**Working Group**

- International Issues
- State Department Lead

- Defense Radionavigation Policy

- Civil Radionavigation Policy

- Primary Information Exchange With Users

**Notes:**
This slide presents the US management of the GPS and show where the USCG and NAVCEN roles are.  As you know the Global Positioning System (GPS) is a satellite-based radionavigation system developed and operated by the Department of Defense.   GPS makes it possible for users to determine their three dimensional position, velocity, and time, 24 hours a day in all weather, anywhere in the world.  The GPS system provides a signal for civil users which has a predicted accuracy of approximately 13 meters, since selective availability was set to zero in 2000.
A memorandum of agreement between DOD and DOT governs the operation and use of the GPS.  DOD is responsible for the military users and operates the system.  DOT is responsible for representing the needs of the civil users and keeping DOD informed of those needs.  NAVCEN coordinates and manages the Civil GPS Service Interface Committee (CGSIC) as part of the DOT’s program to respond to the needs of civil GPS users, and to integrate GPS use into civil sector applications.  NAVCEN CGSIC responsibilities continue under an MOA with DOT that was developed during the Coast Guard’s transition from DOT to DHS.  The next slide provides the organization of the CGSIC in more detail.
The National Positioning Navigation and Timing (PNT) Executive Committee was created by Presidential Decision Directive in December of 2004 to manage GPS as a dual-use system (military and civil users).  The National PNT Committee is chaired jointly by DOT and DOD at the secretary level.  All civil GPS needs are currently represented by DOT in the National GPS management structure.  The Department of Homeland Security participation is focused on the protection of GPS as a utility for national infrastructure.
DHS has created a Geospatial PNT Executive Committee that is Co-Chaired by the DHS Deputy Undersecretary for Preparedness and USCG Headquarters Maritime Domain Awareness Program Office (G-51-M).  This DHS Executive Committee is supported by two Working Groups.  The first is the Geospatial Working Group chaired by the DHS Geospatial Management Office.  The second is the PNT Working Group which is chaired by the USCG.  The PNT Work Group is supported by NAVCEN through our USCG Headquarters Program Office (G-54132) on operational (for example GPS civil input) and technical issues.

## CGSIC is the World-Wide Forum Between Civil GPS Users and U.S. Government Service Providers

- Civil GPS Service Interface Committee

**Notes:**
CGSIC is THE recognized world-wide forum for effective interaction between civil GPS users and the US GPS authorities. The CGSIC Chair is the Director of PNT at DOT’s RITA.  The incumbent CO of NAVCEN serves as the Deputy Chair.   NAVCEN in this role is involved in determining GPS civil user needs and concerns and communicating them to DOD through DOT.  The CGSIC also has a Deputy Chair for International Affairs with a person selected from the International community to serve in the position. 
Each subcommittee represents specific segments of the user base, and meets separately at various times of the year and in locations convenient to the members.

- Civil GPS Service Interface Committee

**Notes:**
The Civil GPS Service Interface Committee (CGSIC) is chaired by Mike Shaw (SES) // OST - policy development. NAVCEN’s Commanding Officer serves as the Deputy Chair of the CGSIC. 

A central role for the CGSIC is to collect information from users and pass it to other government agencies, as appropriate, for their action.  This is primarily accomplished through direct contact with users at both domestic and international CGSIC meetings.

CGSIC comprises members from US and international, private, government, and industry user groups.  

## 
Represent civil interests in GPS management and operations decisions

Collect civil user requirements for GPS

Collect information from users for GPS authorities (DOT Policy Office, GPS JPO)

Support the PNT and DOT Policy Office (OST-P)

- Civil GPS Service Interface Committee

**Notes:**
The Civil GPS Service Interface Committee meets semiannually and is open to anyone interested in civil GPS issues.  A summary record of each meeting is available on the NAVCEN website. 

Each subcommittee represents a specific segment of the civil user base, and these meet separately at various times of the year and in locations convenient to the members.  

The next CGSIC meeting will be in Long Beach, California just prior to the ION Satellite Division Meeting. The meeting is open to everyone.  Attendance is free, but registration through the NAVCEN website is required.

## The Core 

- The Core** **

**Notes:**
GPS information distribution is separated into three areas, each with their own responsibility.

The FAA National Operational Command Center, or NOCC,  is responsible for distributing NOTAMs and coordinating spectrum issues dealing with GPS.

The GPS Operations Center supports the Defense user and handles information concerning operation of the satellites.

The Coast Guard Navigation Information Service located at NAVCEN is the contact point between non-military, non-aviation users and the system operators. 

MOUs currently exist between NAVCEN, 14th Air Force, and the FAA to define the working relationships and to facilitate information exchange.

## Work with DOD to safeguard civil interests in GPS satellite ops and maintenance.

Provide civil liaison to the GPS Operations Center

Coordinate issue resolution between GPS user and service provider

Support civil users in resolving outages by facilitating outage reports, coordinating resolution and findings, and disseminating results    

- Provide civil liaison to the GPS Operations Center
- Coordinate issue resolution between GPS user and service provider
- Support civil users in resolving outages by facilitating outage reports, coordinating resolution and findings, and disseminating results

- NAVCEN Liaison to GOC

**Notes:**
A Coast Guard Navigation Center billet is currently in place at Air Force Space Command.  This liaison billet provides important USCG and civil interface access directly to the GPS Operations Center, working with the USAF to address civil concerns regarding GPS.  
One of the key functions of the liaison is also to facilitate analysis of GPS outage reports received by NAVCEN from civil users.

**Notes:**
The Navigation Information Service (NIS)  provides one-stop shopping for all radionavigation system user needs.  The NIS is staffed 24 hrs a day, 7 days a week, and provides status, policy and general information for : GPS, DGPS, and LORAN-C.  The NIS also disseminates Maritime Safety Broadcasts and Local Notices to Mariners (LNM).

The NIS strives to satisfy customer needs by using the latest computer and INTERNET technologies to gather, process, and disseminate timely information.  Through the NIS website, users can download status, policy, and other important information related to waterway and navigation safety.  The NIS collects user reports of GPS anomalies, interference to GPS and other problems related to safe navigation.  The NIS website also provides users the ability to subscribe, via e-mail, to automated e-mail distribution of the latest  Notice Advisories to NAVSTAR Users.
