The National Space-Based Positioning, Navigation and Timing (PNT) Advisory Board has scheduled a meeting for June 6-7 at the Westin Hotel in Alexandria, Virginia, reports the Civil GPS Service Interface Committee (CGSIC).
The meeting will be open to the public up to the seating capacity of the room. Visitors will be requested to sign a visitor’s register.
The agenda for the meeting includes the following topics:
Examine methods to protect, toughen and augment (PTA) access to GPS/GNSS services in key domains for multiple user sectors.
Examine emerging trends and requirements for PNT services in U.S. and international fora through PNT Advisory Board technical assessments, including backup services for terrestrial, maritime, aviation and space users.
Update on U.S. Space-Based PNT Policy and GPS modernization.
Explore opportunities for enhancing the interoperability of GPS with other emerging international GNSS.
Prioritize current and planned GPS capabilities and services while assessing future PNT architecture alternatives with a focus on affordability.
Assess economic impacts of GPS/GNSS 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.
Review the potential benefits, perceived vulnerabilities, and any proposed regulatory constraints to accessing foreign Radio Navigation Satellite Service (RNSS) signals in the United States and subsequent impacts on multi-GNSS receiver markets.
Meeting times are 8:30 a.m. to 5:30 p.m. Eastern Time on Thursday, June 6; and 9 a.m. to 1 p.m. ET on Friday, June 7.
