2. PNT Advisory Board Panel 2 Strategic Engagement and Communication Strategic Engagement and Communication Tasking Recommend ways to promote and demonstrate current and future capabilities of GPS and its augmentations to the US and international communities. –Near Term: Develop options for promoting GNSS capabilities for domestic and foreign audiences. –Mid Term: Identify actions the USG could take in international organizations, standards setting bodies, and/or foreign capitals to prevent attempts to mandate the exclusive use of any one GNSS system in specific geographic areas. –c) Long Term: Propose approaches for maintenance and improvement of GPS's leadership and acceptance around the world.

3. PNT Advisory Board Panel 2 Strategic Engagement and Communication Panel Progress Discussions with members since March meeting Teleconference to plan and prepare for this meeting results in: –Three topics for fact finding briefings near-term Reference Frame Timing Promotion Options Preparatory meeting Oct 3 Mid-term and long-term discussions Note activities of the International Committee on GNSS (ICG), recent meeting in Bangalore Underscore importance of GNSS Interoperability; strategies for common standards

4. PNT Advisory Board Panel 2 Strategic Engagement and Communication US Involvement in Global Geodetic & Geophysical Sciences, Research and Applications Most contribute to International GNSS Service (IGS)*, since early 1990’s 15 years, significant history of successful strategic engagement. * until 2005 International GPS Service

5. International GNSS Service Formerly the International GPS Service US agencies that contribute to the IGS include: National Aeronautics and Space Administration (NASA), National Geospatial-Intelligence Agency (NGA), National Oceanic and Atmospheric Administration (NOAA) National Geodetic Survey (NGS), Naval Research Laboratory (NRL), National Science Foundation (NSF), US Naval Observatory (USNO), and US Geological Survey(USGS), and numerous universities & research organizations.

Over 350 permanent tracking stations operated by more than 100 worldwide agencies comprise the IGS network. Currently the IGS supports two GNSS: GPS and the Russian GLONASS. IGS products are formed by combining independent results from each of several Analysis Centers. Improvements in signals and computations have brought the centers’ consistency in the Final GPS satellite orbit calculation to ~ 2cm http://igscb.jpl.nasa.gov NASA funds the IGS coordinating center: IGS Central Bureau

6. PNT Advisory Board Panel 2 Strategic Engagement and Communication Panel Plans Review matrix assignment topics and discuss approach for mid-term, long-term tasks –2 - System performance and delivery of services bring requirements in line –2.1 & 2.2 - Commit to 30 satellites! (Both loss of leadership if US steps back) –2.4 - Support laser reflectors in GPS satellites –4 - DO NOT CONSIDER USER FEES! –5.2 - No mandated use of a specific GNSS –6.2 - Spectrum protection, complex, support Panel 3 Note that a more proactive, coordinated effort should be pursued 6.3 Interference Detection - Review San Diego event, other efforts, Ward article, ICG work plan, …

7. PNT Advisory Board Panel 2 Strategic Engagement and Communication Panel Plans (2) Task matrix continued: –7.1 - Plan for ‘education and awareness’ within US Policy, Senior Military, Congress, and new users Strategic engagement with US Military Promotion options aka marketing –7.2 - ITAR (?) Current US implementation of ITAR regulations overburdens and stifles innovation 7.3 - Support need for improved ‘system of systems’ –Engagement with international organizations and standards bodies - e.g., ICG, RTCA/RTCM, IHO, IOC,GEO,…
