In order to solve the vulnerability of Global Navigation Satellite System (GNSS), Enhanced Long Range System (eLoran) has emerged as a major interest. Especially after year of 2010 in South Korea, the cases that makes user hard to find the exact path in marine ways due to GPS jamming signal. For this reason, it causes to develop backup navigational system as a Position, Navigation, and Timing (PNT) infrastructure. Currently, eLoran is the sole navigational system which is technically independent from satellite based navigation system, as well as able to backup and provide PNT service.
This Research and Development (R&D is separated to develop eLoran core technology, build up testbed and perform the verification analysis. Doing this activities, we look forward to consolidating the foundation of independent navigation system, and implementation of stable PNT&D (Data) service infrastructure
