## 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. 

## New PNT Management Structure

**Notes:**
This slides shows a representation of the National Positioning, Navigation, and Timing (PNT) management structure.

The PNT is co-chaired by DOD and DOT.  The PNT Principals are supported by the Senior Steering Group and the Executive Secretariat, both of which are involved in oversight of GPS working groups.  

On the right bottom we see the Civil GPS Service Interface Committee.  

## 
700 Members:  U.S. Federal, State, Non-U.S., Industry, Universities, 59 Nations

Meets once a year in plenary session

- 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.

- 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

- 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.
