November 18, 2019  - By

Which of several proposed terrestrial PNT technologies is best suited to complement and back up GPS?

“Seeking PNT resiliency for critical functions, a layered, multi-source terrestrial RF backup strategy could include eLoran for continental coverage and Locata, or similar system(s), for high-precision, localized service where needed. However, don’t forget feature-aided navigation using optical, radar, lidar, etc., and positioning/timing from ‘validated’ signals of opportunity in data-rich environments.”

“No single technology can provide a backup to GNSS to match the ubiquity of satellite-based PNT. However, placing inertial navigation systems at the core of our PNT solution, and focusing on bounding the growth of the positioning errors using whatever other space or terrestrial measurements are available, could provide an alternative paradigm to resilient positioning and navigation.”
