## GPS Management Structure

- Radionavigation
- Policy

** ****IGEB SSG**** **

**Notes:**
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, now that selective availability has been set to zero,  has a predicted accuracy of approximately 20 meters.
The Interagency GPS Executive Board was created by Presidential Decision Directive to manage GPS.  The IGEB is chaired jointly by DOT and DOD.
NAVCEN’s Commanding Officer is a member of the Senior Steering Group, that assists the IGEB in formulating major decisions regarding the management of GPS and its U.S. Government augmentations.
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 Department of Transportation’s program to respond to the needs of civil GPS users, and to integrate GPS use into civil sector applications.

CGSIC is THE recognized world-wide forum for effective interaction between civil GPS users and the US  GPS authorities. The CGSIC Chair is Mike Shaw (SES), Director of DOT’s Radionavigation Policy Office.  The incumbent CO of NAVCEN serves as the Deputy Chair.   NAVCEN  is very involved in determining GPS civil user needs and communicating them to DOD.  The CGSIC has recently added a Deputy Chair for International Affairs with a person selected from the International community to serve in the position.  The first person serving in this position is Mr. Peter Grognard, Septentrio, Belgium
CGSIC comprises members from US and international, private, government, and industry user groups.  To address the concerns of various users, CGSIC has formed three major subcommittees:  International, Timing, and US States and Localities.

CGSIC meets semiannually and is open to anyone interested in civil GPS issues.  A summary record of each meeting is available on the NAVCEN website.  Information from CGSIC members and meetings is provided to US  GPS authorities for consideration in GPS policy development and GPS service operation.
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.
