Relational Database for PNT Data

2020 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2020
Navigation filter researchers often deal with multiple sets of data collected from different sources. Over time it can be difficult to identify how data was collected and how to model it without sufficient data storage techniques and documentation. A navigation database would allow storage of sets of Position, Navigation and Timing data, along with ...

Delivering resilient PNT

2015 International Association of Institutes of Navigation World Congress (IAIN), 2015
For eLoran to be truly useful as a backup system to GNSS it must offer significant coverage for accurate positioning. Research in differential-Loran is very new and, until we understand more about the characteristics of spatial decorrelation of differential corrections, Port Approach Phase eLoran will be limited in coverage area due to the assumed ...

Complementary PNT Technology Demonstration

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2021
Positioning, Navigation, and Timing (PNT) supports critical infrastructure with its most known service: Global Positioning System (GPS). The presence of signals broadcast from satellites in Medium Earth Orbit (MEO), results in low signal strength from the receiver making it vulnerable to intentional and unintentional disruptions which could lead to ...
