eLoran is an internationally standardized, low frequency terrestrial positioning, navigation and timing service with its roots in the Loran-C system used extensively - in its time - by Navies around the world.

eLoran is not impacted by the same vulnerabilities as GNSS

Modernized transmitters provide more power and will reach deeper inside buildings, providing precise UTC synchronized and traceable time with daily variations on a par with GNSS but where GNSS and other technologies cannot reach etc etc

By using the Loran Data Channel to provide differential corrections, precise time can be delivered to accuracies within 50ns relative to UTC, easily applicable to next generation mobile phone technology and digital broadcasting networks.
