  1. Space-Based PNTPolicy Update JSDE/ION Joint Navigation ConferenceJune 8, 2010 Lt Col Scott L. BoushellSenior Advisor

  2. 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

  3. 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

  4. U.S. Space-Based PNT Policy

  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 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

  6. Defense Transportation State Interior NATIONALEXECUTIVE COMMITTEEFOR SPACE-BASED PNT Executive Steering Group Co-Chairs: Defense, Transportation ADVISORY BOARD Sponsor: NASA Agriculture Commerce NATIONAL COORDINATION OFFICE Host: Commerce Homeland Security Joint Chiefs of Staff NASA GPS International Working Group Chair: State Engineering Forum Co-Chairs: Defense, Transportation U.S. Space-Based PNT Organization Structure WHITE HOUSE Ad HocWorking Groups

  7. 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 Eleven EXCOM meetings since 2006

  8. 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) * *– Future Systems

  9. 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 Pursue through Bi-lateral and Multi-lateral Cooperation

  10. 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 GPS is still the gold standard…and will be for the foreseeable future.

  11. 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 As new space-based GNSSs emerge, compatibility and interoperability are keys to “success for all”
