Blog Editor’s Note: Wednesday’s Federal Register announcement outlined some of the topics that will be discussed at the upcoming US National PNT Advisory Board meeting next month (see below). We can also tell you that included in the list of presentations will be:

  • Professor Todd Humphreys from the University of Texas speaking about how he was able to detect GNSS signal disruption on Earth from the International Space Station, and
  • Dr. Val Parker from NIN Technology speaking on “Non-Inertial Navigation In 21 Century and Beyond.” 

RNT Foundation will hold two events for members at the same venue in parallel with this government public meeting:

  • A reception the evening of the 5th of June from 6:30 to 8:00 that will include members of the advisory board,  presenters at the following day’s meeting, and government officials.
  • RNTF’s Annual Meeting and member’s forum the afternoon of the 7th of June.

We encourage all RNTF members to participate in all of these events. If you are not a member, that’s very simple to fix. Just go to Hope to see you there!

  • Examine methods in which to Protect, Toughen, and Augment (PTA) access to Global Positioning System (GPS)/Global Navigation Satellite Systems (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 back-up services for terrestrial, maritime, aviation, and space users.
  • Update on U.S. Space-Based PNT Policy and GPS modernization.Start Printed Page 21837
  • 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.
