March 2021 – UrsaNav’s CEO, Charles Schue, and Board of Advisors Member, Dr. Wouter Pelgrum, have the pleasure of announcing that the long awaited Two-Volume Set entitled “Position, Navigation, and Timing Technologies in the 21st Century, Volumes 1 and 2: Integrated Satellite Navigation, Sensor Systems, and Civil Applications, Set 1st Edition” is now available. Chapter 41 provides historical and current information on “Navigation with Low-Frequency Radio Systems”, and also provides a peek into what may be coming in the future. Given the authorship of this chapter, it naturally includes a comprehensive study of Loran-C and Enhanced Loran systems. We are extremely honored to have been selected to participate in this incredibly important and comprehensive project that showcases all the various technologies necessary for a resilient PNT ecosystem. The work is available from Wiley (https://www.wiley.com/en-us/exportProduct/pdf/9781119458340) and other fine outlets.

March 2021 – The US Patent and Trademark Office (USPTO) has approved UrsaNav’s Private eLoran patent (United States Patent Application 20190377055). Private eLoran is a new and innovative breakthrough in terrestrial PNT technology that provides secure, un-spoofable, and virtually un-jammable PNT signals. Private eLoran provides a secure co-primary alternative, or complementary backup, to GPS/GNSS for individual nation-states or collaborative regions. Private eLoran significantly reduces the risk/reward equation for those who wish to jam or spoof PNT signals, especially those that are space-based. With this new capability, service providers can now deliver fully-open or fully closed solutions, or a combination of both. This new patented technology is another leap forward in UrsaNav’s progressively innovative eLoran and LFPhoenix™ products and services.
