PNT 2018

Dr. Gregory Gutt presents at National Space-Based Positioning, Navigation, and Timing Advisory Board

Dr. Gregory Gutt (Satelles) presented “Current Operational Status of Low Earth Orbit (LEO) Satellite-based Time and Location” at the 2018 National Space-Based Positioning, Navigation, and Timing (PNT) Advisory Board Meeting, held in Baltimore, Maryland from May 16-17, 2018.  The PNT Advisory Board provides independent advice to the U.S. government on GPS-related policy, planning, program management, and funding profiles in relation to the current state of national and international satellite navigation services.    This year’s agenda included the following topics:

  • Update on U.S. Space-Based Positioning, Navigation and Timing (PNT) Policy and Global Positioning System (GPS) modernization
  • Current and planned GPS capabilities and services while assessing future PNT architecture alternatives with a focus on affordability
  • Methods in which to Protect, Toughen, and Augment (PTA) access to GPS/Global Navigation Satellite Systems (GNSS) services in key domains for multiple user sectors
  • 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
  • Potential benefits, perceived vulnerabilities, and any proposed regulatory constraints to accessing foreign Radio Navigation Satellite Service (RNSS) signals in the U.S. and subsequent impacts on multi-GNSS receiver markets
  • Opportunities for enhancing the interoperability of GPS with other emerging international GNSS
  • Emerging trends and requirements for PNT services in U.S. and international fora through PNT Board technical assessments, including back-up services for terrestrial, maritime, aviation, and space users
