PNT Adv Board 10/16/ Advisory Board Topics Leadership Strategic Engagement and Communication Future Challenges 10

PNT Adv Board 10/16/08 Leadership: Recommend areas where GPS and its augmentations can be made more competitive a)Near Term: Examine navigation-communications services for civil applications, including the issues related to safety critical certification requirements, the overall business case, technical feasibility, and analyses of potential alternatives b)Medium Term: Review and prioritize future GPS III satellite capabilities, expanded ground segment capabilities, and/or regional augmentations that would provide the greatest improvement and value relative to increased benefits to the global user community at reduced risk and cost c)Long Term: Identify actions that would enhance long-term economic and regulatory stability for the development of GNSS capabilities and services in the national and international arenas 2007 Advisory Board – Topic 1 11

PNT Adv Board 10/16/08 Strategic Engagement and Communication: Recommend ways to promote and demonstrate current and future capabilities of GPS and its augmentations to the US and international communities a)Near Term: Develop options for promoting GNSS capabilities for domestic and foreign audiences b)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 2007 Advisory Board – Topic 2 12

PNT Adv Board 10/16/08 Future Challenges: Assess technology and market trends as the number of worldwide GNSS providers increase a)Near Term: Recommend steps agencies should take to achieve spatial interoperability – Including harmonization of common grid operations that would be used to identify locations and coordinate time- critical operations b)Mid Term: Assess the implications to the USG public sector and overall U.S. economy of multiple GNSS providers c)Long Term: Propose approaches on commercial trade issues to ensure a level playing field in the space-based PNT market place (i.e. prevent adverse restrictions) 2007 Advisory Board – Topic 3 13
