U.S. Space-Based PNT Policy

4

GOAL: Ensure the U.S. maintains space-based PNT services, augmentation, back-up, and service denial capabilities that…

ASSURE SERVICE Provide uninterrupted availability of PNT services

MEET DEMANDSMeet growing national, homeland, economic security, and civil requirements, and scientific and commercial demands

LEAD MILITARILY Remain the pre-eminent military space-based PNT service

STAY COMPETITIVEContinue to provide civil services that exceed or are competitive with foreign civil space-based PNT services and augmentation systems

INTEGRATE GLOBALLY Remain essential components of internationally accepted PNT services

LEAD TECHNICALLY Promote U.S. technological leadership in applications involving space-based PNT services

U.S. Space-Based PNT Policy• No direct user fees for civil GPS services• Open public signal structures for all civil services

– Promotes equal access for user equipment manufacture, applications development and value-added services– Facilitates open market-driven competition

• Encourage use of GPS time, geodesy and signal standards• Promote global compatibility and interoperability of future systems with GPS• Protect the current radionavigation spectrum from disruption and interference• Recognition of national and international security issues and protect against misuse

5

U.S. Space-Based PNT Policy• Recognizes the changing international scene

– Other nations are implementing space-based systems that provide PNT services

• Established National Executive Committee (EXCOM) for Space-Based PNT– Chaired by Deputy Secretaries of Defense &

Transportation– Broad membership to include civil and military interests– Supported by National Coordination Office with staff from

member agencies• Very active senior U.S. Government leadership

– National EXCOM Meetings: Nov 07, Mar 08, Jul 08, Nov 08• Executive Steering Group Meetings: Oct 07, Jan 08, Jun 08, Oct

For More Information• PNT.gov is a source for information about U.S.

space-based PNT policy and programs, including:– U.S. policy, EXCOM membership, Advisory Board– Cooperation agreements, joint statements, and U.S.

offer letters to ICAO and IMO– Information about Selective Availability and other

frequently asked questions– Recent public presentations

• GPS.gov provides information on GPS applications– Available in English, French, Spanish, Arabic and

Chinese– Brochures also available in hardcopy upon request– Links to various other web sites

14

Summary• U.S. policy demonstrates U.S. Government

commitment to space-based PNT for all stakeholders– Provides framework for public and private decision makers– Improves coordination across U.S. Government– Promotes international cooperation for worldwide

compatibility and interoperability

• U.S. Government Senior leadership is highly engaged and effective in implementing U.S. space-based PNT policy and programs
