Space-Based PNT Policy Update JSDE/ION Joint Navigation Conference June 8, 2010 Lt Col Scott L. Boushell Senior Advisor

Introduction During the past decade, GPS has grown into a global utility providing space-based positioning, navigation and timing (PNT) –Consistent, predictable, dependable policy and performance –Augmentations improve performance Like the internet, GPS is a critical component of the global information infrastructure –Scalable applications enabling broad new capabilities –Innovations in efficiency, safety, environmental protection, public security and science 2

U.S. Space-Based PNT Policy History 1978:First GPS satellite launched 1983:President offered free civilian access to GPS 1996:Established joint civil/military GPS management 1997:Congress passed law providing civil GPS access free of direct user fees 2000:President set Selective Availability to “Zero” 2004:President issued U.S. Policy on Space-Based PNT 2007:President announced elimination of Selective Availability capability from future GPS III satellites 3

U.S. Space-Based PNT Policy 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 DEMANDS Meet 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 COMPETITIVE Continue 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 4

U.S. Space-Based PNT Policy Recognizes the changing international scene –Other nations are implementing space-based systems that provide PNT services Established National Space-Based PNT Executive Committee (EXCOM) –Chaired by Deputy Secretaries of Defense and Transportation –Membership includes: State, Interior, Agriculture, Commerce, Homeland Security, Joint Chiefs of Staff, and NASA Established National Coordination Office (NCO) with staff from each member department/agency 5

Key Executive Committee Activities National Space-Based PNT Five-Year Plan –Summarizes EXCOM agency planning for development, acquisition, sustainment and modernization of U.S. space- based PNT systems Interference Detection and Mitigation (IDM) Plan –Department of Homeland Security coordinating U.S. capabilities to detect and mitigate sources of interference to GPS and it augmentations National PNT Architecture –Provides national PNT framework/investment strategy to help guide future PNT system-of-system investment International Cooperation and Consultation –Promotes compatibility and interoperability with other foreign systems 7 Eleven EXCOM meetings since 2006

Existing and Future GNSS Global Constellations –GPS (U.S.)– Galileo (EU) * –GLONASS (Russia)– Compass (China) * – GINS (India) * Satellite-Based Augmentations –WAAS (U.S.)– GAGAN (India) * –EGNOS (EU)– SDCM (Russia) * –MSAS (Japan) Regional Constellations –QZSS (Japan) * – IRNSS (India) * 8 * – Future Systems

U.S. Objectives 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 signals Achieve interoperability – ability of civil U.S. and non- U.S. space-based PNT services to be used together to provide the same user better capabilities than would be achieved by relying solely on one service or signal –Primary focus on the common L1C and L5 signals Ensure a level playing field in the global marketplace –Transparency for open services 9 Pursue through Bi-lateral and Multi-lateral Cooperation

Challenges Strategic Communications –Improving National Communications mechanism Closer NCO collaboration with USAF/AFSPC/GPSW on message –Pursuing more effective global information campaign Transition from defensive to offensive strategy Education and Outreach –Smithsonian Time & Navigation Exhibit –GPS Adventures –GNSS Regional Education Centers 10 GPS is still the gold standard… and will be for the foreseeable future.

Summary U.S. Space-based PNT efforts progressing well in policy, programs and international outreach –Implementation of 2004 U.S. Policy proceeding well –U.S. space-based PNT system performance continues to improve into the future –International cooperation is a priority Actively engaged in bi-lateral and multi-lateral consultations –New GNSS applications emerging –Must synchronize the strategic message 11 As new space-based GNSSs emerge, compatibility and interoperability are keys to “success for all”
