U.S. Policy Promotes Global Use of GPS/GNSS Technology

• No direct user fees for civil GPS services– Provided on a continuous, worldwide basis

• Open, public signal structures for all civil services– Promotes equal access for user equipment

manufacturing, applications development, and value-added services

• Encourages open, market-driven competition

• Service improvements for civil, commercial, and scientific users worldwide

• Global compatibility and interoperability with GPS

Chamber 03/09

U.S. Objectives in Working with Other GNSS Service Providers

• Ensure compatibility ― ability of U.S. and non-U.S. space-based PNT services to be used separately or together without interfering with each individual service or signal– Radio frequency compatibility– Spectral separation between M-code and other GNSS signals

• Achieve interoperability ― ability of civil U.S. and non-U.S. space-based PNT services to be used together to provide the user better capabilities than would be achieved by relying solely on one service or signal– Primary focus on the common L1C and L5 signals

• Promote a level playing field in the global marketplace

Goal of Civil Interoperability

Ideal interoperability provides users a PNT solution using signals from different GNSS systems– No additional

receiver cost or complexity

– No degradation in performance

Interoperable = Better Together Than Separate

Interoperable = Better Together Than Separate

International Public Sector Cooperation

• Bilateral to include– Europe– Russia – Japan– India– Others

• Multilateral– International Committee on

GNSS– Asia Pacific Economic

Cooperation– ICAO, IMO, and ITU

Chamber 03/0910

U.S. - Europe Cooperation

• 2004 U.S.-EU agreement provides foundation for cooperation

• Four working groups were set up under the agreement:– Technical, trade and security issues working groups have met

• Improved new civil signal (MBOC) adopted in July 2007

• First Plenary Meeting successfully held in October 2008

Oct. 22, 2008 , EU-U.S. Plenary delegations meeting under the auspices of the GPS-Galileo Cooperation Agreement

Signing ceremony for GPS-Galileo Cooperation Joint Statement, Oct. 23,

Chamber 03/0911

U.S. Bilateral Cooperation

• U.S.-Japan Joint statement on GPS cooperation in 1998– Established foundation for stable policy leading to Japan as a global

leader in commercial GPS/GNSS markets – Japan’s Quasi Zenith Satellite System (QZSS) designed to be fully

compatible and highly interoperable with GPS– U.S. working with Japan to set up QZSS monitoring stations in Hawaii

and Guam in exchange for data access

• U.S.- Russia Joint Statement issued in Dec 2004 – Negotiations for a U.S.-Russia Agreement on satellite navigation

cooperation underway since late 2005

– Considering new civil CDMA signals to be interoperable with GPS/Galileo

• U.S.- India Joint Statement on GNSS Cooperation in Feb 2007– Important topic is ionospheric distortion/solutions to this phenomena

– Technical Meeting focused on GPS-IRNSS compatibility and interoperability held in January and July 2008

Chamber 03/09 12

Multilateral CooperationInternational Committee on GNSS

• Promotes GNSS use and integration into infrastructures, particularly in developing countries

• Encourages system compatibility and interoperability

• Membership: GNSS providers, international organizations and associations

• Providers Forum– United States, Europe, Russia, China, India, Japan– Focused discussions on compatibility, interoperability

• Next meeting: Sep 2009 in St. Petersburg, Russia

Multilateral CooperationAsia Pacific Economic Cooperation

(APEC)•Apr 28-29 – APEC Transportation Ministers meet in

Manila

– 18 Feb invite extended to CEOs to participate; deadline 13 Mar

– POC – Joe Traini – DOT – (202) 366-0603

•Jun 2010 – U.S. to host APEC GNSS Implementation Team meeting in Seattle

– Issues: Road safety, reducing congestion, fuel economy, etc.

– Working with the U.S. National Center for APEC

• Facilitating American private sector input into APEC

– POC – Maureen Walker – NCO – (202) 482-2004

Chamber 03/09

Private Sector Competition

• Minimize competition between service providers• Encourage fair competition in the private sector

in GNSS receiver and application markets – Leads to greater innovation, lower costs

• Fair competition means no preferential treatment for any particular company (s)– Equal (if not open) access to information and markets

• Freedom of choice desired for end users– Standards and other governmental measures should

not effectively mandate use of one GNSS over another

• U.S. agreements with other GNSS providers include language on fair trade/open markets (non-discriminatory)

Chamber 03/09 15

Summary

• U.S. Space-based PNT Programs, Policy Implementation and Diplomatic efforts are progressing well

– Continuing to improve GPS and Augmentation Systems

– International cooperation is a priority for the U.S.

• Compatibility, Interoperability

• Equal Market-Driven Competition in receivers & applications

• GNSS use continues to expand with many new applications emergingAs new space-based GNSS emerge

globally, public sector cooperation is the key to “success for

all”

As new space-based GNSS emerge globally, public sector

cooperation is the key to “success for all”
