## Why Cooperation?

**Why Cooperation?**

**Today**
**GPS**
**GLONASS **
**DGPS and GBAS**
**SBAS (pre IOC)**
**Combined GPS/GLONASS receivers**
**Pseudolites**
**Combined with other technologies (ex. - GSM)**
**Tomorrow**
**Operational SBAS**
**GBAS – LAAS, GRAS**
**Galileo**
**Japanese Quasi Zenith Satellite System **
**Future Concepts**
**RTK on Nationwide DGPS**

**Users benefit if systems are compatible and interoperable**

## U.S.-Europe Cooperation

**U.S. and E.C. have been working towards a mutually acceptable framework agreement on cooperation**
**Recent negotiations: **
**November in The Hague **
**January in Washington DC**
**February in Brussels**
**Major issues resolved**
**Trade & non-discrimination**
**Access to signals and information**
**Spectrum/signal structures**

## Current Status

**Agreed to baseline signal structures for L1**
**Common BOC(1,1) signal**
**Optimization studies**
**PRS at BOC(15,2.5) cosine phased modulation**
**Changes allowed within national security criteria**
**Commitment to preserve U.S. and allied military NAVWAR capability**
**Agreed to not restrict use of or access to open services by end users, including augmentations**
**Agreed to non-discrimination in trade in civil satellite navigation goods and services**
**Remaining issues**
**Mixed agreement with European Community and EU member states**
**Finalization of reference documents and handling of classified reference document**
**Ratification process**
**Goal is to sign at U.S. – EU Summit in June**

## Japan

**Strong cooperative relationship based on Joint Statement**
**21-22 January 2004 Technical Working Group Meeting on GPS-Quasi-Zenith Satellite System (QZSS)**
**Discussions on ensuring compatibility and interoperability between GPS and QZSS signals and timing elements**
**Documents were drafted and signed that include the interface and technical assumptions **
**Documents form the basis for configuration management between the two systems**
**Launch date of 2008 is planned for QZSS**

## Brazil

**U.S. Delegation visited Brazil in October 2003 to discuss use of GPS, further collaboration on application research, and the potential for a cooperation agreement **
**Three days spent in Brasilia meeting with various ministries representatives**
**Two days in Sao Paulo meeting with US Counselor, American Chamber of Commerce,  and industry representatives**
**Planned US-Brazil GPS conference scheduled for September 2004 in Sao Paulo**
**Next round of consultations scheduled for April 2004**

## India

**India-United States Conference on Space Science, Applications, and Commerce**
**Jun 21-25 2004 in Bangalore**
**Technical Symposia: **
**Earth Observation **
**Satellite Communications **
**Space Science**
_**Satellite-based Positioning, Navigation, and Timing**_
**Natural Hazards Research and Disaster Management Support**
**Tele-medicine and tele-education**

**International Expert Meeting (Vienna 11-15 Nov 2002)**
**International Workshop (Vienna 8-12 Dec 2003)**
** ****Objective - to promote use of satellite navigation services, in particular in developing countries, through education and assistance with the integration of GNSS into their infrastructure**
**State Department POC is Ken Hodgkins**

## Summary
