Today NASA published a meeting announcement in the Federal Register (79 FR 67469) for the National Space-Based Positioning, Navigation and Timing (PNT) Advisory Board in Washington, DC on December 10th, 2014. Readers of this blog may be interested in this meeting because the GPS system is used for timing coordination in many control systems.
The agenda includes:
• Examine emerging trends and requirements for PNT services in U.S. and international arenas through PNT Board technical assessments.
• Update on U.S. Space-Based Positioning, Navigation and Timing (PNT) Policy and Global Positioning System (GPS) modernization.
• Prioritize current and planned GPS capabilities and services while assessing future PNT architecture alternatives with a focus on affordability.
• Examine methods in which to Protect, Toughen, and Augment (PTA) access to GPS/Global Navigation Satellite System (GNSS) services in key domains for multiple user sectors.
• Assess economic impacts of GPS on the United States and in select international regions, with a consideration towards effects of potential PNT service disruptions if radio spectrum interference is introduced.
• Explore opportunities for enhancing the interoperability of GPS with other emerging international GNSS.
The meeting is open to the public and no advanced registration is required, but there is limited seating. There are no indications that the meeting will be web-cast or be made available via other electronic means; odd from a technology based organization like NASA.
