2007 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 communitiesa) Near Term: Develop options for promoting GNSS capabilities
for domestic and foreign audiencesb) 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 increasea) 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)
