A Resilient Complement to GPS/GNSS

eLORAN is an independent and dissimilar complement and co-primary capability to GPS/GNSS. It allows users to retain the safety, security, and economic benefits of GPS/GNSS, even when satellite services are disrupted. There are no common failure modes between eLORAN and GPS/GNSS, meaning a disruption that causes a failure of one system will not impact the operation of the other. This is a core principle of a resilient system.


Enhanced Long Range Navigation: eLORAN is the 21st century evolution of a proven technology known as LORAN-C. LORAN-C was operated by the United States Coast Guard for over 60 years as the world’s premier radionavigation technology for PNT.
